The amount of yarn needed for a blanket will depend on the size of the blanket, the thickness and type of yarn you select, and the type of crochet or knitting you’ll be doing.
Here are a few tips to help you figure out how much yarn you’ll need:
Measure your blanket to determine the size and decide how many stitches per inch you will use. This will give you the best estimate of the yarn you may need.
Consider the type of yarn you’re using, as the weight or thickness of the yarn will determine how much you’ll need.
If you’re using the same yarn throughout, figure the number of skeins you’ll need by figuring out the inches of yarn per skein and multiplying it with the estimated number of skeins required.
If you’re using a different color for each section, make sure you purchase enough yarn for the entire project.
Read the recommended care instruction for your yarn before you start, as this will also affect how much yarn you may need.
You can also find a number of helpful calculators online to estimate the amount of yarn required for a crochet or knitting pattern. These calculators also consider the yarn weight and gauge you have selected. For instance, this calculator by Esty can help you estimate the amount of yardage required for a crochet project: https://www.etsy.com/ca/listing/667688856/yarn-calculator-crochet-pattern-yarn.
Once you’ve estimated the approximate amount of yarn you’ll need for your project, it is always a good idea to buy some extra yarn to account for any uncertainties. This way, you can finish your project without worrying about running out of supplies!
