The selphy app makes it easy to print those different sizes. When I used to use a selphy sometimes I’d cut at the edge of the photo instead of the perforation, so you keep the perforated part on. It isn’t super noticeable on the finished layout. But if you’re going to trim it down to mat it anyway then it works out!
I’m not too stressed about them being slightly smaller, I’ve gotten used to it. My biggest annoyance so far is actually the fact that so far all my photos are curved and I need so much glue runner to get them to lay flat! I just ordered more paper/ink so maybe it was that… other people don’t seem to have such curved photos! I might upgrade some day but so far I’ve enjoyed using this printer!
Thanks for showing this! I had no idea I could do a collage through the selphy app. Also, mine has been gathering dust because it kind of drives me crazy that it’s not a true 4x6, I hadn’t thought to trim it to be slightly smaller on purpose and have them matted!
