I get as far as joining two different coloured pieces. When I have joined all list this I see they will not fit to make straight lines. Yes I do move and then pin into new places . I try to be so careful and sew one pair at a time. I am making placemats. To begin with. The a1 and a2 are stopped top to bottom b1and b2 go left to right .
Then I join sorry I'm so thick I think it could be results of the anaesthetic last Wednesday. This is just not like me.
