How many yards of yarn does it take to make a pillow?
A standard bed pillow measures 20-by-26 inches; it needs 5/8 yard of 54-inch fabric. A queen-size pillow is 20 by 30 inches; it needs 1 1/8 yards. A 20-by-36-inch king pillow needs 1 1/4 yards. More fabric may be needed to match patterns or stripes, but pillows usually are so small that’s not an issue.
How much yarn do you need for a pillowcase?
Take one long length of yarn, about 75 inches ( You won’t use it all, but better to have too much than not enough!) start at the bottom corner and start to weave your yarn through the knitted loops of your pillow cover.
