This is actually much easier to do than it looks! if you like how it looks, this article is for you! What you need to do this awesome bag of paint materials for their children is: two pieces of cardboard, a little larger than A4; enough fabric in different colors to cover both sides of the board, to make a pocket, spaces for pencils and markers, and the handles of the bag, a sewing machine. You can also do this without a sewing machine, but it's much easier if you can use one.
The first step is to make the handles, pockets and spaces for her pencils and markers to then sew the piece of fabric that covers the inside of the bag. The handles in the example were stuck inside but sew them will make them stronger.
If the inside is ready, you have to sew the inside lid. You must leave one side without sewed so you can place the cardboard inside the cover turns once again. Leaving the top could be better as it does not have to be so strong, so you can stick that side carefully with fabric glue, making sure they have a good finish. This may be the most difficult to do!
If you think it is necessary, you can add six pieces of tape, two on each side open and create a way to close all sides of the bag so you do not miss anything while transporting.
Now all you need is to fill the bag of the artist with the necessary supplies and wait for the reaction. This is also a good idea for a gift!
