Aren't these felt fruit ssssoooooooo cute! I love them and so does Karsyn. They too a little bit more time than some of the other pieces but worth it.
There are six slices of fruit in each "shell: and I sewed a button and ribbon loop on each to hold the opening closed but a piece of elastic would work too.
I painted the seeds on with puff paint. I used this pattern I purchased at Etsy for these fruits and used the pattern to make my own watermelon design
The seeds were painted on with black puff paint. The outside of the watermelon has 2 alternating colors of green and 3 of the slices of watermelon have light green rinds and 3 have dark green rinds.
