What to Check Before Buying Yarn Online

A yarn listing can look appealing, but a beautiful color is only one part of a good purchase. Before ordering, check the fiber content, the amount of yarn in each skein, and whether the yarn weight matches your pattern. For hand-dyed yarn, also review dye-lot information and color variation notes. These details help you estimate how much to buy, avoid surprises when your parcel arrives, and choose yarn that works for the way you plan to knit or crochet.

Read the Fiber Content

Look for the exact fiber blend, not just a general description such as “soft” or “natural.” Wool, cotton, alpaca, silk, and synthetic fibers each behave differently. Fiber affects warmth, drape, stretch, care, and how clearly stitches show. If you are making a garment, consider how the yarn will feel against skin and whether the finished piece needs to withstand frequent washing.

Check the care instructions before buying. A yarn that requires hand washing may not suit a frequently worn baby item or a project you want to machine wash. If the listing does not provide fiber percentages or care guidance, ask the seller before ordering. For a project with specific needs, such as socks or a lightweight summer top, confirm that the fiber is suitable rather than relying on the product name alone.

Compare Yardage, Not Skein Weight

Skein weight tells you how heavy the yarn is; yardage tells you how much length you are buying. Two skeins that each weigh 100 grams can contain different amounts of yarn because their fibers and thicknesses differ. Compare the listed yardage with the pattern’s total requirement, and calculate how many skeins you need before placing an order.

If a pattern gives its requirement in meters and the listing uses yards, convert the units before comparing. Also allow for swatching, finishing, and small differences in gauge. When the project is close to the listed amount, an extra skein can help prevent a shortage, especially if you may not be able to get the same color again.

Match Yarn Weight and Gauge

Yarn weight describes thickness, from very fine yarns to bulky options. Match the weight named in your pattern, but treat the label as a starting point: yarns within the same category can still vary in thickness and texture. Check the seller’s recommended needle or hook size and the stated gauge, then compare those details with the pattern.

Plan to make a gauge swatch with the yarn and tools you intend to use. If your stitches are too large or too small, the finished item may not match the pattern’s dimensions. A different fiber or construction can also change the fabric’s drape. For fitted garments, swatching and checking the fabric before buying enough yarn for the full project can prevent costly rework.

Check Dye-Lot and Color Notes

Hand-dyed yarn can show subtle differences between skeins, even when they share a color name. Review the listing for dye-lot details and notes about natural variation. If your project needs several skeins, ask whether they come from the same dye lot and order the full quantity together when possible. This reduces the chance of a noticeable color shift between sections.

Screen settings and lighting can make a yarn appear different from its actual color. Read the seller’s color description and look for photos that show the yarn in more than one view. If you are combining colors, compare them in person when possible or contact the shop for guidance. For larger projects, alternating skeins every few rows can help blend mild variation.

Before you check out, confirm the fiber and care requirements, compare total yardage, match the yarn weight to your pattern, and review dye-lot notes. Save the listing details with your pattern so you can refer to them later. If you have questions about a particular project, Glasgow Dye House can help you check whether a yarn is a good fit.
