does anyone know where I can find mirror boxes?

I haven't seen mirror boxes recently in stores at a reasonable price, but I have made these inexpensively in the past. Depending on the use of the boxes, you can either buy cardboard, wood or tin/metal boxes from a craft/hobby store and ask a glass shop to cut mirror to size then assemble yourself using construction adhesive. Depending on the sizes of the boxes you want, you might also be able to find pre-cut mirror pieces at your local craft or hobby shop. Making them yourself also allows you to have different sizes for different purposes and you can further embellish them with glued on rhinestones or other decorative pieces (artificial flowers, ribbon...) to match your color scheme.

Even dollar stores sometimes have a decent selection of boxes you can use, as well as a small selection of mirror tiles in the craft aisle.

Good luck & congratulations!

I saw it last night too! Absolutely beautiful! I've been searching myself and didn't come up w/ anything yet. The 3rd responder came the closest w/ the pyramid tea light mirrors. TLC Wedding Channel may be the best way to get an answer. I'm sure we're not the only ones who are asking for these. Jung, the wedding planner probably has her own site as well. Does anyone remember the name of the show?
