Knitters have a special lingo for the size of the yarn that they are using, which is referred to as “weight.” Knowing the lingo is your first step to cracking the code of what yarn to buy for your new project.
I’ve put together the most popular lingo that you need to know to knit. Patterns and yarn will include at least one of these terms, numbers, or symbols to indicate what you need so that you can buy the right type.
Fun fact! If you inherit yarn with no label, you can use the wpi (or wraps per inch) measurement to discover what yarn you have on hand. Simply take a ruler and wrap the yarn around it as many times as you can until you’ve wrapped up an inch of the ruler. Don’t pull the yarn too tight, and do have it lined up neatly. Then simply count how many times you were able to wrap it around the ruler in that inch, and you have the wpi!
Also, the knitting needles that are usually used with each type of yarn are a guideline, not a rule. Using smaller needles than recommended will result in dense, tight knits which may buckle and not be square. But using larger needles than recommended is a technique used to make looser, lacy knits. Feel free to be creative! (Unless your pattern tells you exactly how many stitches should be in 4 inches, which is called gauge, and makes sure that your project ends up the right size).
