I think it really depends a lot on the individual person. I love making log cabin blocks and have never had a problem with them being crooked. I do not prewash my fabric before cutting it into strips (using the June Tailor Shape Cut mat). I do not use a foundation. I do chain-type production sewing using strips; I never pre-cut my log cabin blocks. The blocks always come out really nice and I have no problems sewing them together. If someone is getting a crooked block, then the easiest solution is to make the last strips a little wider, then cut the block down to correct size. (I have never had to do this.)
I tried the Judy Martin log cabin book and started a quilt using her methods. It just about drove me crazy. There is a ***lot*** of work involved in cutting all those logs! Went back to my strip piecing method and am much happier.
