Cuts 5 & 6: Make a cut from the bottom of the shirt along each side seam (I recommend cutting just to the front of the seam in order to eliminate it from the apron.) stopping 1 1/2 to 2 in. from cut 4.
Cut 7: Cut straight across the back to connect cuts 5 & 6.
Cut 8: Cut the remaining strip of fabric between cuts 4 and 7 in half to create the ties for the apron.
And you have yourself an apron! From here, you can easily add any embellishments and finishing touches you want. Or if you just need a good crafting apron for the kids, it works well as is.
As you can see, my little princess has no embellishments on hers right now, I mean it was designed and developed by a man, but both kids love them. And, my man was pretty proud of himself. Like I said...ALL him. Ingenious!
