A few years ago, I used basic shapes to make fun criss cross earrings that utilized color changes by layer for fun and simple effects.
I wanted to make a “Christmas Tree” version (which is basically a triangle) and finally did. Can be made festive for Christmas or go crazy with colors to make them work for any time of year.
You change colors between layers so they stand out and I like to use ironing on all surfaces. You should change colors 3 times so you do color 1, color 2, color 1, color 2.
