My husband wasn't a huge fan of the colors. He thought it was more for a girl. I didn't really mind because it was scrap fabric in my stash :) Yellow and black are boy colors right? My husband also thought a velcro closure could have been better because what 2 year old can tie a bow? I had to give him that one. Next time. . .
I also found that regular crayons are a bit too short for the length of my pockets. The crayons tend to get stuck at the bottom. I used larger/thicker crayons for measuring this. I can always stitch a .5-1" seam along the bottom to lift the crayons up a bit.
Hours of fun. I think my son enjoys putting the crayons away and getting them out more than actually using them for coloring.
