Have you tried the Envelobox Creator yet? It's so cool! I've had it for a bit now, but I FINALLY got a few minutes to give it a try. It was actually incredibly easy to use.
I used a few different paper from the Sweet Treats paper pack. These papers are thick and strong and score really well - they are perfect for any type of 3D project!
I also added on a few small embellishments from the Downton Abbey Luxury cardmaking kit (those are coming soon).
This is great for a thicker card, that has several layers and embellishments on it. You can make almost any size box in several thicknesses. The Envelobox Creator is a fantastic tool and I'm so glad I tried it!
All supplies available on the Crafter's Companion website.
