FreePrints app/4x6 suggestions

The company FreePrints gives 85 prints a month 4x6 size-just pay for shipping which is about $10 so cheaper than anything around me. Thought I’d suggest it to yall!

Also anyone have suggestions for 4x6 prints for junk journals? Most free printables I’ve found are for standard 8.5x11 so would be tiny as 4x6. EDIT was hoping to print “sticker” collages I’ve seen on Pinterest, without cutting a row off in the middle.
