Did you make those, Wifezilla? Holy cow!
My parents had a decorating store, and I still have a few sample books that I go into for projects. Once you have them for a while, all kinds of ideas will come to you. You might want to get a small tube of the vinyl paste if they are vinyl, regular glue doesn't always work.
I made lots and lots of envelopes using a basic pattern from a commercial one. I would address it with a sharpie, though.
I covered tons of coffee cans and made my pantry storage very pretty. Lots of compliments, and I made some for others, too. Makes a great gift tin for giving cookies, etc. I don't even drink coffee, either.
Book covers, yes. Also you can make folders for projects, for coupons, for receipts....anything you need to organize and want it to be pretty.
Last summer's yard party I made the switch to NO disposables....we used glassware. I made butterfly cutouts that slipped over straws and used a sharpie to write everyone's names on them. Ooops, guess the straws were plastic and disposable. Oh, well, our impact was still minimal! They can also go on bamboo skewers! Flowers would work, too.
Gift tags.
Sturdy boxes were covered and used to organize drawers and cupboards....oh, yeah, and shelf liners and drawer liners, too, although I quickly switched to using the flooring samples for forever liners!
A sturdy shoebox was covered and filled with cleaning supplies as an apartment warming gift for a young man going into his first apartment, a friend's son.
Paper beads! A friend took some books home and made wonderful paper beads that looked like ceramic! You make a long strip of paper, maybe start with 6-8 inches by 1/2 inch to get an idea...wrap it tightly around a piece of wire such as coat hanger, gluing as you go. For oval beads, have it be somewhat triangular in shape, going from 1/2 inch down to 1/8 inch. Once you make a couple, you will see what your measurements need to be.
When they are thoroughly dry, coat them with shellac or such, until nice and glossy for a ceramic look. Or use a matte finish, the possibilties are endless.
Yes, I have matted photos and drawings with it, too. If you scrapbook, more possibilities.
That should get your creative juices flowing! Have fun!
