Help!! I'm making a panel to use as a valance for my kitchen window. It will be D9Ps on point (I hope!). How do I figure for the size of the setting triangles? My block is not a usual size. The squares are cut 4" so the block is 10 1/4" square (well, give or take a few...). As Mary Ellen would say, "It's my measurement. Would cutting a 10 1/2 " square be big enough. I don't have fabric to waste, so I'm trying not to cut and experiment. Can anyone help? Thanks in advance.
