Now you are ready to start the other side... figure out a way that you other side will come out even... your last color square should meet in the middle and the ribbon will hide the pins....
This is what I do.... I take the scissors and mark the stryo ball with an X on the side that isn't done... then I put my first square right in the center of the X.... I hope that makes sense....
When you do them with four materials...just adjust the amount you go down with each material....
My advice to you is... the neater the fold... the prettier the ornament....
