This is a doily stretched onto a hoop to make into a mandala.
I haven’t included gauge because the finished size isn’t important. I have made it twice, once using above mentioned hook and yarn, and once using a 2mm hook with lincraft cake illusions yarn. I found using the 3mm hook, my piece was looser and the 2mm was a fair bit tighter and curled up whilst working on it but if you pull on it after each round it falls into a better shape. Also if it is wobbly, blocking it once finished fixes this issue.
