In drafting my pattern for Lasse the Whale, I realized I had to include how many yards/meters of each color would be needed to complete the pattern. Beyond a rough, eyeballed guess though, I had no idea how to go about measuring this. My first idea was that perhaps one went through the whole process of knitting the toy, and then unraveled the entire thing and measured the yarn used on a yardstick. (I actually wondered for a couple of days if professional knit designers might regularly do this.)
Then, when one of my test knitters reported back her yarn use in grams instead of in meters, I realized with a jolt how simple it in fact is to figure out how many meters of yarn you have used. Weigh it!
If the finished product is multiple colors and stuffing, so you don’t know how much of the weight is blue and how much is white, weigh the remaining bits of your skeins instead.
The label around the skein said: 100g = 120m. And if 100 grams equals 120 meters, than 26 grams equals 31.2 meters, I must have used the rest, namely 88.8. I can say you need 90 meters of blue yarn. A little bit of elementary school math. Easy peasy.
This was totally an AHA! moment for me. I realize that for many of you reading this, it’s more likely a DUH! moment, after all, now that I see it, the solution is totally obvious. But maybe this tip is helpful to those, who, like me, had never thought of it before.
