There's no point in trying to make your own reeds if you don't play. The finer nuances of playing pressure, tone, volume, etc. are going to be a problem for a non-piper. However, there are cheapie reeds available for some smallpipes, depending on bore size. Practice chanter reeds are the standard for Gibson Fireside pipes and Kitchen Pipes. Used to be for the the Bagpipes Galore Practice Pipes, but they now have a different setup.

As for sealing the bag, in many cases, if the leather is sound, a good application of Airtight bag seasoning will be all it takes.

FWIW.

For $25, I'd go for it myself, but I am a piper and could probably make them work for me. That is, if they could be made to work at all.
