If by chance you have a Facebook account, there is a Kilts and Accessories For Sale and Wanted group (and probably others similar), and also Facebook Marketplace where, if you’re patient, you can sometimes turn up decent kilts for reasonable prices. My “better” kilt is a nice heavyweight 100% wool in Black Watch (though I think of it as Munro Hunting, since I had Munro ancestors) that had been someone’s wedding kilt. It wasn’t cheap (I don’t remember the cost, and it was part of a package deal) but it was far less than it would have been new. Recently I decided I wanted a “pub kilt” that I wouldn’t be so worried about spilling a pint of Belhaven or a dram of Ardbeg onto, and got a wool blend MacDonald Ancient (I also have Donald in my lineage, though from Ayrshire so probably no clan connection) for $50. Patience is key, though, and double-check the size (the wedding kilt was stated to be my size, but turned out to be considerably larger and fell right off me, and I had to have it taken in by a woman who alters kilts for all the local pipe bands here).

As for sporrans, if you’re feeling handy (being an artist you probably are) there is a Sporran Craft group on Facebook with lots of interesting posts from people creating their own. Definitely skewed more toward those making fancier dress sporrans, but there have been some interesting day sporrans as well. I would imagine you might find some reusable leather in a thrift shop (old leather jacket, handbag, or some such thing) that could be repurposed into a pretty decent and unique day sporran. Crafting your own, you can make sure it’s large enough to carry what you need.
