At our crafty meetings each month, we decided to hold a 4" swap each month. I decided to design mine around corrugated board. Using a mixture of acrylic ink mixed with white gesso to partially cover. I had prepared lots of embellishments so I ended up making quite a lot of pieces. The above was the same as the swap piece (but I liked it so much I made another that eventually I used on the canvas below).
Above is a 16" square canvas I made with other pieces. It was a gift to my lovely daughter in law.
I got a bit carried away and went on to make several cards with similar designs but using a finer corrugated cardboard, 15 in total, all slightly different and still enough embellishments over to make more.
