I finally had a chance to try the unironed binding. I did a small preemie quilt and ironed half the binding and left the other half not ironed. Other than I found doing the mitre a bit tricky with the unironed section, I really didn’t find the machine stitching part difficult. When I started the hand sewing I don’t see any difference. This was a fun experiment and I found all the comments and info quite interesting. Going forward I probably won’t iron my binding anymore. I think the mitre will get easier with practice and ironing is not my favourite activity.
