This one is part flannel. The black triangels are not. Some of the plaids are and some are not. Easy and quick. This is the second quilt that I made. The plaids are strip sewn and then you cut the triangles and sew to the black triangles to make the square. It would be a good one to use old shirts too. The black and white border is flannel and the back is the same flannel fabric. This is DH favorite and he had me make his brother one for Christmas last year. I had it done in less than a week.
