Interesting things. I think of them as a way of promoting an Etsy shop within the Etsy community (which has some limitations but is not a bad place to start, and depending on what’s in one’s shop, may be a great place to start).
Anyway, because of this, probably look at them with a slightly different eye. I love it when they come together, with the little 4×4 collection of items makes a pretty picture that is very much larger than the sum of the parts. This one is particularly nice: Are you my Secret Santa? The alternating color repetition gives all the items very Christmas-y feel, when several would not suggest that at all when standing on their own.
This treasury which included me, has lots of items I like, items with wonderful photos. Isn’t as strong as the first, the rhythm is a bit out of sync, I so want to move things around!
