I found some pocket mirrors at Michael's and thought they'd be really cute gifts for Mother's Day if I put pictures on the fronts.
I printed off a photo slightly smaller than the inside of the indent, then laminated, and trimmed it to size.
then I put doubled sided carpet tape (found it at Home Depot in the flooring department) on the back (that stuff was super sticky!) and stuck it to the front of the mirror.
it wasn't exactly how I imagined it, but it was still cute!
