This paintbrush holder was very easy to make. I bought this fabric in St. Thomas the year we went to Tortola with my mother-in-law and all her kids and grandkids. The ribbon is lovely, but it was only by chance that it was the one that most closely matched the colors in the fabric.
Then I folded up about nine inches to form the pockets, sewed up the sides, and sewed eight interior lines from the bottom to the opening to make nine compartments. I used my brushes as a guide. They were mostly 12 inches long. If I make another one of these, I'll take pictures and provide more detailed directions. I sewed the ribbon just through the middle of the ribbon to the right side only. When I roll up the holder, I fold the top down over the brushes and then roll it up starting from the left side where the smaller brushes are. When it is all rolled up, the ribbon is on the outside and I just tie it around. When I'm using the brushes, I fold the top back and tie the ribbon to the easel. The whole thing just hangs there with a little slant so that the brushes don't fall out, and I can pull out whatever size brush I need. For this to happen the ribbon has to be closer to the top than to the bottom.
