Trouble sewing on the bias
I am a brand new quilter working on my very first quilt and I need some advice. I've scoured the board (and internet) but I can't seem to find an answer, which makes me think I'm missing something really really basic. (Although I've learned loads from reading the posts on this board!).
The part I am having trouble with is sewing two little squares on the diagonal into the corners of a large rectangle ( flying geese effect when done). When done the fabric doesn't lie flat - I can press out the puckering but there remains a very slight 'buckle' in the fabric of the large rectangle (like I have stretched the fabric). Am I missing a trick - or is this just the way it works ? I have used the same stitch length and tension that worked well for joining squares together for another part of the quilt.
All suggestions gratefully welcome.
