I’ve made these twice now and they’re always a hit! They’re even fun to have sitting around the living room for people to look at. First I made them as a Valentines day gift for Alen and then once my Mom saw those and loved them I knew they’d make a great Mother’s day gift too! Below are the few that I’ve done, so simple and inexpensive! Home Depot has the tiles for something crazy like .14 ea!
As for sizing the photos I have photoshop which I know a lot if people don’t have access to. If you print them out 4×4 you’ll be fine or there are a ton of similar programs online for free!
