Thread Selection



Choosing the right thread can feel overwhelming, but it's one of the most important steps in getting the results you want. For the majority of our work we reach for 40 weight polyester because of its versatility and durability — yet we love exploring the wide world of specialty threads, each bringing its own texture and finish to a design.


The best thread always depends on your project. The fabric you're stitching, the density of the design, and the overall look you're after all play a part. From soft cotton for a matte finish to specialty threads that add a touch of shimmer, the possibilities are endless. Use this guide to navigate thread selection with confidence and elevate every finished piece.




MATERIALS LIST

◆ 40 wt polyester thread (the versatile, all-purpose standard)

◆ Rayon thread — for vibrant color and high sheen

Machine Embroidery Needles - Match the right needle to every fabric, thread, and project

Machine Embroidery Needles - Match the right needle to every fabric, thread, and project

ANITA GOODESIGN | Anita's Tutorials Machine Embroidery Needles Match the right needle to every fabric, thread, and project SKILL LEVEL Beginner Friendly NEEDLE TYPES Six Profiles BEST FOR Needle Selection Embroidery needles are among the most important tools in your machine. Each type is built with specific features — the shape of the point, the size of the eye, the depth of the groove — that make it suited to particular fabrics and threads. Choosing the right needle is one of the easiest ways to improve your results. The correct needle can be the difference between a clean, even stitch and a frustrating session of thread breaks and skipped stitches. This guide walks you through the anatomy of a needle and the most useful needle types, so you can confidently match the perfect needle to every project. NEEDLE TYPES IN THIS GUIDE ◆ Universal Needle ◆ Metallic Needle ◆ Leather Needle ◆ Ball Point / Jersey Needle ◆ Gold Titanium Needle ◆ Sharp (Microtex) Needle Anatomy of a Needle Before choosing a needle it helps to know its parts. Every machine needle shares the same basic anatomy: the butt (A) at the very top slots into your machine, the shank (B) is the thicker section that seats the needle in place, and the shaft (C) tapers down toward the point. The long groove (D) runs down the front and guides the thread, the eye (E) is the hole the thread passes through, and the point (F) and tip (G) determine how cleanly the needle pierces the fabric. Use the labeled diagram below as your reference. 1 Universal Needle The Universal is the all-rounder of the needle world. Its medium-sized eye and slightly rounded point handle a wide variety of fabrics, which makes it a dependable choice for general sewing and light embroidery on both woven and knit materials. Reach for it for everyday sewing tasks, light embroidery on cotton, and mixed-fabric projects. 2 Metallic Needle Metallic threads are beautiful but delicate, and this needle is made specifically for them. A larger eye and a specially shaped groove give the thread room to move, which dramatically reduces breakage and snagging. Use it for any project featuring metallic threads — decorative embroidery, embellishments, and costume designs. 3 Leather Needle The Leather needle has a distinctive wedge-shaped point designed to pierce tough materials cleanly. It slices through leather and thick synthetics without tearing or shredding them. It is the go-to needle for leather garments, bags, and sturdy upholstery fabrics. 4 Ball Point / Jersey Needle Instead of piercing the fabric, the Ball Point (or Jersey) needle has a rounded tip that slips between the fibers. That gentle action prevents damage and avoids the skipped stitches that stretchy material often causes. It is ideal for jersey knits, stretchy materials, and delicate fabrics like spandex. 5 Gold Titanium Needle Coated in Titanium Nitride, this needle is built to run smoothly and last longer than a standard needle. Its slightly rounded point and enlarged eye are gentle on even the most fragile specialty threads while standing up to heavy use. It performs especially well on coarse, densely woven materials. 6 Sharp (Microtex) Needle When precision matters, the Sharp — also called Microtex — delivers. Its fine, acute point penetrates tightly woven fabrics for crisp, accurate stitching. Use it for detailed embroidery on silk, taffeta, and other delicate, densely woven fabrics. 💡 PRO TIP Keep a small assortment of needle types on hand and match the needle to your fabric and thread before you start stitching. The right needle minimizes thread breakage, prevents skipped stitches, and gives you a smoother, more enjoyable sewing experience — it is the simplest way to raise the quality of your work. You're Ready to Choose the Right Needle! Match the needle to your fabric and thread, keep a few types on hand, and every project will stitch out beautifully.

Machine Embroidery Scissors - Build the cutting toolkit every embroiderer needs

Machine Embroidery Scissors - Build the cutting toolkit every embroiderer needs

ANITA GOODESIGN | Anita's Tutorials Machine Embroidery Scissors Build the cutting toolkit every embroiderer needs GUIDE TYPE Beginner Friendly TOOLS COVERED 11 Scissor Types FOCUS Cutting & Trimming Just as a chef relies on a well-equipped set of knives, every embroiderer should have a dedicated collection of scissors on hand. Having the right pair for each task makes a real difference in both the efficiency of your work and the quality of your finished pieces. This guide walks through eleven cutting tools, one at a time. For each, you will see what it looks like, a clear description, and exactly when to reach for it — so you can build a toolkit that is ready for any embroidery challenge. A COMPLETE SCISSOR TOOLKIT ◆ Embroidery scissors — fine, pointed tips ◆ Snip scissors (thread snips) ◆ Treadle / spring-loaded snips ◆ Curved embroidery scissors ◆ Appliqué scissors ◆ Narrow-blade scissors ◆ Serrated-edge scissors ◆ Fabric shears ◆ Pinking shears, plus left-handed options 1 Embroidery Scissors These are small, sharp scissors with very fine pointed or slightly curved blades. Keep them as your go-to for precision work: trimming threads right up against finished embroidery, snipping tiny pieces of fabric, and cutting around intricate details. The pointed tips let you get in close for fine work without nicking the surrounding fabric. 2 Snip Scissors (Thread Snips) Compact, spring-action scissors built for quick, one-handed use. Because the spring reopens the blades for you, they are ideal to keep right at the machine for fast trimming between stitches. Reach for them whenever you need to clip thread ends and small seams without breaking your rhythm — they will save you real time over a long project. 3 Treadle Scissors (Spring-Loaded Snips) Similar to standard snips, but designed to rest open when not in use, so they are always ready to grab and easy to store. They shine in busy, fast-paced sewing sessions where you want quick, repeated thread snipping without fumbling. Think of them as a convenient upgrade when speed and easy access matter most. 4 Curved Embroidery Scissors These have gently curved blades that follow the shape of fabric edges. The curve lets you trim appliqué pieces and layered fabrics cleanly without accidentally cutting into the base fabric underneath. They also help you achieve smooth, clean edges around rounded shapes and tight corners. 5 Appliqué Scissors A specialty pair with a distinctive curved (often paddle-shaped) blade made for cutting precisely along the edges of appliqué pieces. Use them to trim away excess fabric right next to your stitching, which keeps your lines crisp and helps prevent the raw edges from fraying. They are the tool of choice for tidy, professional-looking appliqué. 6 Narrow-Blade Scissors These feature long, slim blades made for precise cutting in tight, awkward spaces. They are perfect for detailed trimming in confined areas and for safely cutting threads or individual fabric layers without disturbing the material right next to them. Keep them handy whenever a regular pair feels too bulky to maneuver. 7 Serrated (Fiskars-style) Scissors Scissors with a finely serrated, micro-toothed edge that grips fabric so it cannot slide away as you cut. They are especially useful on slippery or silky materials, where smooth blades tend to push the fabric forward. The serrations give you more control over each cut and noticeably reduce frayed, ragged edges. 8 Fabric Shears Larger scissors built specifically for cutting fabric, with long blades and ergonomic, comfortable handles. Use them to cut out bigger pieces of fabric before you begin an embroidery project. Good shears hold their sharpness well and handle a wide range of textiles, so it is worth keeping a dedicated pair just for fabric. 9 Pinking Shears Easy to recognize by their zigzag blades, which cut fabric in a saw-tooth pattern. That patterned edge is mainly used to finish raw fabric edges: it adds a decorative touch while also limiting fraying. They are a great choice for tidying edges that you plan to embroider later. 10 Left-Handed Scissors These are made specifically for left-handed users, with the blades reversed so the cutting line stays visible and the cut feels natural in the left hand. Any of the types in this guide can come in a left-handed version. If you are left-handed, using scissors built for you makes cutting more accurate and far more comfortable. 11 Cutting Mat & Rotary Cutter Not scissors exactly, but an essential cutting companion: a rotary cutter works much like a pizza cutter and is used together with a self-healing cutting mat for precise cuts. It excels at slicing through multiple layers of fabric quickly and accurately, which is ideal when prepping pieces for embroidery. The mat keeps your lines clean and protects both your blade and your work surface. 💡 PRO TIP You don’t need every pair at once. Start with three workhorses — fine embroidery scissors, a pair of thread snips at the machine, and good fabric shears — then add the specialty scissors as your projects call for them. Keeping your fabric scissors separate from your paper scissors will also keep them sharp for years. Your Scissor Toolkit Is Ready! With the right tool for every cut, your embroidery will be cleaner, faster, and more enjoyable. Machine Embroidery Scissors | Anita's Tutorials | Anita Goodesign
