Those are adorable! Need to have those for all children under 30 LOL!
LOL! Hope you can post a photo of your little "monster" wearing them!
The first words that come to mind are "Happy Butt" ~ whimsical and cute! Great job!
I've been watching them on pinterest, I do not do this, but love them yours are sew cute.
These are great fun and I hope your grandson enjoys them. He will bring a smile to many faces wearing these
