|I've been practicing watercolor now for 6 or 7 years. I just love the medium and have amassed quite a pile of past watercolor artworks. I usually sketch and paint something, take a picture of it, post it to Instagram, then toss it in a pile.|
Pick out a cover. I use heavy duty fabric, like canvas or home dec weight. Something a bit stiff works best. Trim your cover to match the size of the paintings. It should be ever-so-slightly larger but not by much! I use a rotary cutter here to get an exact cut.
Place the bundle inside the cover. Open the whole ensemble and lay it on a self-healing mat. (I use a punching cradle as seen in the picture) Along the center crease, using a sharp awl, pierce through the entire bundle, cover and all, in three spots. Pierce the first hole roughly in the middle and the other two holes about a half inch in from each edge.
