Unlike mastering the 1/4 inch seam or cutting strips with out the dreaded V , I really do think FMQ require more "maintinience" to keep the skills. I am with you , as I thought I was progressing ... didn't do any for a few months ...and the results looked like I had never done FMQ before. I suppose I should keep a practice sandwich ready and do a bit on it at least every week or more. It just seems like this skill is always just beyond my grasp.
