So went back to searching for materials -- if only I had a large enough balloon to use, like one of those punch balls . . . that would be sturdier and make a nice sound. But no, nothing like that . . . I tried a normal sized balloon but it was way too small.
After taking out all the fabric scraps I had, I came across a brown piece of vinyl from an old purse-- yes, this would probably work, so I pulled it out. Also there was a smallish scrap of fake fur in brownish tones, so I decided to use that on the other end of the drum.
I cut out a circle a couple inches bigger around than the canister top diameter, from the vinyl, and made the fake fur circle about an inch bigger than the canister bottom diameter.
But how to get the end pieces to stay on? I knew they would also have to be as taut as possible, so thought buttons could be used as something to put lacing around, holding both pieces onto the drum; the ends would both be pulling towards each other.
The next step was to pencil a circle on the underside of each of the fabrics, the same size as the canister top. I got out some buttons and found 20 that kind of matched the brownish theme, and sewed 10 around each circle (on the right side of the fabric) on both the vinyl and fake fur.
Then I needed to lace the whole thing together. We had some cotton twine, and this was a good fit for the small buttons I was using. Doing the lacing was really not so easy; I had to get out some duct tape and tape the fabric circles in place so it would be easier to lace while also pulling the ends towards each other.
But it worked! After lacing all the way around, I tied a knot at the top, and since there was a lot of twine left, I was able to make a slip knot a few inches down so there could be a loop-- for holding onto the drum, or hanging it up.
Have you ever made a similar drum -- or one that is different? What did you use? What kind of result did you get?
