Any sources you care to suggest will be forwarded to this grandmother, who deserves plaudits for her willingness to make a kilt for her grandson.
I have seen poly-viscose in a few tartans for sale at "Walton Market". You might also decide to consider some blue denim as a rough and ready alternative.

There are small childrens sporrans available... but for a rough and tumble six year old, I'd be inclined to leave it at home except for church etc.

A sturdy belt is probably a good idea.

good luck
