I used all of my Adventure Time blocks - worked a row of single crochet around all of them, then stitched them together and added a border.
You could also crochet them together.

LOVE the border pattern - soooo simple but very effective!
Border pattern can be found in the ‘Giant Granny Patches’ pattern link posted above.
