Hi; I am a fairly new weaver(about 1 year). I recently tried an overshot pattern. The pattern was done correctly, but it came out really elongated. It was supposed to form a circle but was a long oval. The weft patterns threads were all separated instead of filling in a section. I'm thinking it's because I can't beat very hard on my small 22" Norwood loom. I almost always come out with a smaller number of ppi. But usually it doesn't affect the look of the pattern. Anyone else have this issue?
