This is seriously cute and very simple.
Are you ready? Here we go...
Gather your equipment together; contrasting fabrics and ribbons
Cut the fabric into squares. I did them 12"x12" each
Cut all your ribbons the same length
Fold the ribbons in half and pin onto the fabric. Make sure the fold is in the middle part of the fabric.
Sew over the ribbons a few times. You want to make sure the ribbons are very secure.
Then overlap your contrasting fabrics best sides together.
Sew all the way aroubd leaving a gap on one edge.
Cut the corners for a neat corner once its the right way round.
Heres your gap, turn the right way round and iron.
Sew around the edges of the square paying particualr attention to the gap.
