Clothes for little boys are so hard to find! Either they are way too "cutesy" or the colors don't work for me. One of my friends found these Guess coveralls and passed them along to me.
I added fabric to the collar and cuffs, with extra fabric inside the bottom 3" of the hem, so they show when turned up.
To cover up the wording on the back, I made a scenic patch from felted wool scraps on the back, showing our favorite spot at the river.
