I purchased my blue-grey felt at Moskatel's in Downtown LA for $0.29. It was my first time there, and I only had a few minutes to grab what I needed. Parking is free for 2 hours with purchase-validation, so it was easy. For the interior fabric, I used scrap Ikea fabric leftover from curtains.
(The photos are not very instructive bc this is the first time I took pictures along the way. Next time, I'll be better.)
First you want to make the interior, but you want to leave some fabric on the short ends in order to sew on the exterior later. To do so, you need to use french seams but not flip inside out at the end in order to create that extra fabric on the ends. If that's confusing, use this tutorial to visually understand french seams first.
Fold the interior fabric in half with the "wrong" sides facing each other. Sew along the short side. Trim the fabric.

Sew about 1/4" away from that seam. Essentially you're sewing in the cut edges. Done. Now you just have to do the same thing to the other side. (Don't be like me. I put the wrong sides together at first so I had to pull out all my stitches. Pain in the a$$.)
