We used 2 fabrics, one for the outside and one for the liner.
We first drew out a pattern by measuring the grid that will be inside to hold the markers.
This project was quite the challenge, but it was fun seeing it come together. The top has zippers on both sides and velcro across the front flap.
There are also pockets on each end for any extras (right now my color matching shots are there).
Then comes the fun part - putting the grid in and adding the markers!!
We put long handles on the bag to facilitate carrying!
