hey there! i had a quick question. looking at the pic of your arm pattern, it says 9 inches. I drew the pattern like i saw it in the picture but 9 inches doesnt look long enough. maybe the piece is too thicc? doing alittle math, i came to the conclusion that it was 2 inches wide, but that looked too skinny so i did 2.5. now I dont know what im doing wrong. could you give me some tips/notes?
