I used scrap fabric to make these homemade cards (right), and old book pages (left) to create the envelope. I used a fine-line black marker to make dashes around the scrap fabric heart (adhered with fusible web).
I made crocheted hearts using #10 cotton thread, and embellished paper clips for each of them. (Many of these card ideas are shared on S.C.R.A.P. Blogspot).
(The book the mini crocheted heart pattern is in, is linked in the above paragraph)
I thought they could use these for organizing their homework, or for bookmarks. I also thought our oldest daughter could use them for organizing bills and paperwork.
