Does it ever happen to you?
You go to a friend who kindly offers you her floor for basting the big quilt. Although you don't like basting very much you have a great time chatting with the friend (some white wine might be involved, too, but not too much). You finish basting, fold the quilt, checking if everything is nice and smooth, and it is. On the next day you start quilting. The pattern is big squares, set randomly against the squares in the quilt top. The first square has some minor puckers but you can live with it. Instead of unpicking you continue quilting, doing 3 more square before checking the back. You shudder with horror and spend the next evening unpicking the whole lot.
And then, not wanting to bother your friend again, you invent a strange re-basting method, involving a curtain rack and a table.
I tried quilting a few squares yesterday and they look OK now, so it's going to be the quilting weekend.
And since the quilt is taking me much longer than expected, I'll show you the back.
