This is a gift I love to make for people, and this season, some special nieces' new bedrooms. They are bulletin boards, but much more attractive than those cork ones. They can be hung in living areas, like the above board in my home, which I keep recent photos and invitations hung on. This variation uses ribbon and buttons to secure mementos.
preferred size canvas batting (sized to cover the frame of the canvas' back) fabric (ditto) staple gun ribbon for trim push pins
Place the fabric wrong side up, then the batting, then the canvas front squarely. Now you're looking at the back of the canvas. Begin stapling the length of one side, leaving about an inch from the corners.
I like to staple one piece of coordinating ribbon to draw the eye to something--you artists know about the golden third. Now add a handful of push pins (I actually use long sewing pins because they push through the canvas easily and stay well.)
There you have it: a great gift for any room of a house. And children love these to keep photos, drawings, and little treasures.
