I found the directions for making this box and candles HERE and had to try it.
I did find however that the tealights, found at Walmart for $2.25 for 50, did not fit in the box so I had to make a slight adjustment to the length.
For the box cut a piece of cardstock 3-3/4" x 8 -3/8" On all four sides score at 1/2" and 1-1/8". I found it easier to turn my cardstock and score the sides this way than adjusting for my new measurements.
For the lid cut the cardstock 5" x 6-1/8". The adjustment is only 1/8" to the length but the tea lights fit!
