Whether you're spinning for Tour de Fleece, Spinzilla, or for a particular project, you'll have to figure out how much yardage you have eventually. This locking stitch marker trick will help you keep count no matter how much you've spun.
Once the singles are plied and the yarn off the bobbins or spindle, skein up all that precious yardage. Instead of counting every wrap in one go, grab some locking stitch markers and let them keep keep track of the yarn. Just count 20 wraps, or whatever number you like best, and bundle them together with the stitch marker. Repeat till every strand is corralled. Count the markers and you’ll know exactly how many wraps you have without losing count somewhere in the triple digits. No need to wonder if you’ve counted every wrap or double-counted by mistake. The stitch markers are doing all the work.
Now all the need to go is a little math. Multiply the number of wraps by the circumference of the skein and you’ll have your yardage. If you want the yardage of all the individual singles, multiple the final yardage by the number of plies.
