Made a practice 10 minute block with some spare charm squares I had left over from another project. Yes, it is much harder with smaller squares but I'm sure it would look better using 10" ones. It really did take less then 10 minutes and 3 seams!

How, where and when do you press it so the centre square (whichis double fabric and has a lot of hidden seams) lays nice and flat ready for rolling and stitching?

I know this example is very uneven but I wanted to see if I could understand the instructions - they always make it look so easy.
