I made my tubes myself, and I don't have a sewing machine either, nor do I really sew. It's easy. I just used an oversize poster tube,, cut it to the length I wanted with a hand saw. Got some fleece and measured it to the length I needed leaving about 6 inches extra on the ends. Wrap it around the tube snugly and mark off where you need to stitch. Stitch the sides together so you have a fleece windsock looking thing, then slide it over your tube, tuck the excess into the tube and pull it out the other end. Then on the end where you can see the tube, take the 2 excess ends and put them together and pull them over the top so it stays secure, that way it's easy to take it off and wash it of needed. I didn't have any washers or bolts to hang it, so I doubled up some fleece and heavily stitched the fleece to the fleece on the tube and tied it tight to the cage. My boys love their tubes, and 2 of them took me maybe an hour tops to make. If you don't want to do that, then there are plenty of people here that make them.
