Today I unexpectedly received a box of #ArtSupplies. I had sent the order on boxing day, expecting it to arrive next year, and I hadn't received any notification of it being sent.

Anyway, one of the things in the box is a big (A2) picture frame. I distinctly remember putting it in the chart months ago after carefully measuring *something* (possibly it was two or more matching somethings), so I kept it in the chart when ordering thinking “oh, well, while I wait for it to arrive I will see the thing(s) around the house and remember why I bought it”.

so... any suggestion on what was supposed to go into it? it's probably not something I painted, since I mostly do A6 or smaller, and it's definitely something that I already have.
