I posted on FB that I started collecting vintage grain sacks. Some friends brought me the Basmati bags, the other friend got me this large coffee bag from Netherlands. She does a lot of traveling there buying old furniture for her store (www.mooblisahver.com). Thanks Piret!
So first we made a box using 2x4-s and 1x2-s from the construction room.
The coffee sack material is sturdy but very sheer and wimpy, I sewed a different fabric under it to make it sturdier by sewing a grid all across the material.
I get foam from work, we pack heavy stuff there so foam is free. It was a pain to make the trim. It sheared like crazy. But in the end it looks pretty neat I think. If the cats start scratching that I will be very very mad.
