I had a play this weekend with my Sweet Treats Embossing board. I used the small milk carton and made this hexagon box by scoring 3 parts and attaching together. I used Holly Embossalicious folder for the sides and Marianne Pointsetta die.
This next box is a triangle box again using the small milk carton. I scored the two parts then moved my card over and scored another one part and joined together. Embellished with Sentimentals Christmas stamp. Flowers and ribbon from stash.
Here is a side view.
