Your blocks are beautiful. Sephie, I just changed needles (after FMQing for quite some time) and the new needle doesn't like my seams. Done for today but tomorrow I am going to change my needle to a 90/14 sharp. The ones I have been using are 80/12 microtex. The first needle did fine but nothing but trouble now. Missed stitches over my thick seams. Try a comparable sample and I agree with Dunster regarding SITD. I use a wavy pattern on my seams but your pattern would be best with straight stitching in the ditch. One secret I have learned from these wonderful Board members is to look ahead of your needle (don't watch the needle!). I am telling you that it works really well. I also mark my foot with a line to run down the seam. Good luck.
