Love this scrappy version will have to try that. I have made several of these mostly for gifts and the grandson who loves to run his hand over them. I also use flannel in the middle and if you stack all three strips as you will sew them before you cut them, they will already be in place and ready to sew/quilt as you go as long as you pick them up carefully. I usually try to snip somewhere between the 1/4 adn 1/2 inch mark.
I usually pick a size square for the big square and then for the alternate squares use a 4 patch sewn normally, alternating them as I sew the blocks together.
Most of mine are crib or lap sizes, not sure I want to snip a bed size one. The raq snips are a must, or I will use a seam ripper and go out from the line of stitching to the edge, then I don't have to worry about snipping the stitching. Make sure it is a heavy duty seam ripper.
