Created to cover stools 13” in diameter and 1” thick. There is no gauge with this pattern because the size of your stool is subjective. As is the nature of crochet, the covers are very prone to stretching. The cover will look too small at first but with some muscle will stretch to fit tightly. Eventually after some wear they will stretch out. If your stool is comparable in diameter but is thicker than 1”, try adding rounds at end of pattern (after round 12) to accommodate thickness. Make one cover for however many stools you have. One skein of I Love This Cotton should make two covers with some leftover.
