I don’t think I’d put peanut butter by itself in a crepe; the reason peanut butter and jelly sandwiches are so popular is that the jelly/jam helps cut the stickiness of the peanut butter.
But then again, I ate sandwiches that only had peanut butter in them for most of elementary school. Wash it down with some milk, and it’s filling and tasty.
It’s not ideal, but I use Patreon to donate to a few different folks at once (I think it still combines transactions to reduce fees…). Otherwise I usually pay the fee, if the amount I’m donating is small and I’m given the choice.
