yes! that would be great, I do that for shoe boxes, so they look nicer. But these kleenex boxes sometimes have nice designs already, so i like them. i just put cute stickers on the logo sometimes :) thank you for your comment :)
I've been cutting one across the middle so it will fit inside another, then cutting the inside box a little shorter than the outside box. I glue the flaps inside . The boxes are much sturdier. I have covered them all in the same pretty pattern of sticky paper from Dollar Tree so they all match and have their own labels. They look so nice on the shelves with their labels for all kinds of "little stuff" like cards, beads, make-up, pens, pencils, ribbon, fussy cuts, etc.
