-Take 2 - 2.5" strips, minimum length I would say is 2.5" (yields 2, 4-patches) but for every 1.25" in length you get another 4-patch
- put the strips right sides together and sew down each side with 1/4" seams.
-Cut the tube down the middle, (1.25") don't open seams or iron yet!
- now cut 1.25 units from each strip unit, no don't iron yet!
-Take the 2-patches, open and finger press to the darker fabric.
-flip the patches so's to nest the seams, with opposite prints touching - right sides together.
-sew along the edge that makes the seam flap pointing away from you. You know the drill.
-OK now you can iron.
I think by cuting the strips before you open the seams you get a more accurate cut and because the patches are so small, finger pressing is suficient at that point and saves a lot of time too.
I made 120 4-patches this way in about 3.5 hours. It's easy and it's fun and they are so cute. Of course working from a free scrap bag makes it even more fun and the first cuts have already been made which saves time too! cheers, CW
