I searched high and low for a tutorial that used 24 crayons and could not find one. The most that I could find was one for 16 crayons and it was just a single row. I realized how long it would be to put 24 in a single row, so my solution was to make a second row. This folds in half and then rolls. I totally forgot to take pictures while doing all the steps, so I am going to do my best to explain it and hope that you understand. (Must remember to take photos while creating)
How to make it and what you need.
The backing and outside (rocket print) - 2 pieces - 10x14 in each
The crayon pockets (red star print) - 2 pieces - 4x14 in each
1 elastic hair tie
1 box of 24 crayons
Press over a 1/4 inch on the top of the crayon pocket fabric. Then sew it down.
Attach the crayon pockets to the right side of the backing. You should be looking at both prints.
Pin and mark where to stitch the individual pockets. Measure in 1 1/2 inches for the first mark, then 1 inch after that until you reach the other side, leave 1 1/2 inches on the far side.
Stitch to from the bottom of the pocket to the top of the pocket to create the slots where your crayons will fit.
Turn around and do the same for the other pocket.
Pin right sides together and stitch all the way around, leaving an opening to turn inside out.
Turn inside out and then press to make sure it all lays flat. I left my opening where I placed my hair tie.
Top stitch around the edge and over the hair tie.
