Crayon pouch with small note pad.
You can find a tutorial in a ton of places online. For this one, I used a fabric place mat I found at Walmart and a small notepad I found in a 3 pack at the store for about $2. The crayon slots are about an inch wide each and with the notepad, I fit all but the black and white crayons from a 16 count box. I thought about cutting off the top extra fabric but I used it as a flap to ensure the crayons don't fall out and the paper stays clean for the next use. I figure if I run out of paper I can always use index cards, or computer paper cut smaller in a pinch.
I used the tutorial from Make it and Love it. The tricky part is that the towel is thick and gets thicker with each fold. It also lints and can snag if you aren't careful. Some parts I had to reinforce by hand because the thickness would not fit in my machine (I'm not an expert and there may be some other foot or modification I could make to my machine but I didn't take the time to figure it out.)
My daughter was not cooperative as a model.
I have yet to try this on my daughter because she is not being helpful in that regard especially when she is wearing one of her favorite dresses already. This was SUPER easy and really fast. I want to try it on her and maybe modify it a little for more shape but as it is the whole thing took 15-20 minutes (with a toddler distracting/helping) and would probably take 10 minutes had I done it during her nap. I used grosgrain ribbon because I had it on hand.
