I had a think about it and came up with this , not a lot of natural but I did use string!!
The idea for the box which is called a "Peek A Boo" treat box is from the Scor Pal site.
This is the top of the box with the gorgeous little House Mouse image. He has been coloured in with promarkers and layered onto some SU Dashing paper. The box itself has been made with red card and I used a SU wheel with red ink to make a pattern all over it. Then I tied the string around and knotted it up. Just a layered bloom with a little gem to finish off.
Here is the inside of the box. I used a piece of acetate to make the window and stamped over it the same way as the box. I then added some more string and another layered bloom. The tab was made from a Word window punch from SU.
