It's very simple to make. Just take a MAM square and a white square the same size. Place on top of each other and slice both at the same time at an angle. Swap the top left piece for the bottom left piece and sew together so you get two blocks half MAM and half white. Then arrange them going alternately horizontally and vertically to create the zig zag effect. Simple! I quilted it it zig zags on the white to emphasise the design.
This quilt is on my challenge lists. It's granny squares and there were only a couple of blocks completed so was a bit of a slog. I need to quilt it before I can cross it off the list. Lovely.
