I like tube quilting. Sew two jelly roll strips together and press (Group A). Sew a second two together and press (Group B). Sew Group A to Group B on both sides, right sides together. Use a 90 degree angle with the point barely touching the second A-B seam and cut the triangle. Repeat the length of the tube, alternating sides of the seam. You should end up with eight triangles that give you 8 squares (fabric on the diagonal) when pressed open. Arrange them into two blocks & sew together. Repeat until you have the size quilt you want. For a lap quilt, I use 10 strips of each of 4 colors and an additional 5 strips of one color for the binding. You should end up with 24 blocks plus binding.
