Well done on your last two blocks, Libster! I know the feeling... I even ordered and received my fabric for the next boom already! I saw the perfect thing and went for it.
TG, I am having machine trouble too. Just cant get the stitches to balance on my Juki. They are either too tight on top, or too tight on bottom. When I get them adjusted to something halfway decent, the tension reverts to bad, mid-seam! Sooooo frustrating. I am shipping it to the place I bought it, hoping they can figure it out. No good repairmen here. I know as much as they do! I'm secretly hoping it falls off the UPS truck so I can collect the insurance and get a replacement for that lemon.
I'm using my good ole Bernina 830 Record now. Nice stitches on it.
