The business of being a child surely involves being creative, efficient, and productive -- in your own way, of course. Office supplies can help. These envelope books are great for organizing stickers, stamps, coins, and magazine clippings.

Collector Book How-To
Stack a few envelopes of the same size, reinforce corners with a sticker, then punch a hole in each, and insert a keychain or loose-leaf ring. Choose unusual envelopes, such as compact-disc envelopes with windows, small coin envelopes, or airmail envelopes, and dress them up with rubber stamps, vinyl lettering, labels, or photo corners.

Key-Tag Jewelry How-To
A wristful of paper-and-metal key-tag charms makes its own music. The ones on this bracelet are adorned with two sizes of stickers. Or personalize a keychain with a couple of tags decorated with a monogram and star stickers.

To make the bracelets, you will need key tags, a chain bracelet and jump rings (available at jewelry-supply or crafts stores), needle-nose pliers, and stickers. Remove the rings that come with the tags, and decorate the tags. If your decorations cover the holes on the tags, use a mini hole punch to repunch the holes. Using the pliers, open a jump ring, insert a tag, and loop it to a link of the bracelet, then close the jump ring.

Bubble Pack Purse How-To
Once you learn the basic techniques, you can make a purse of any size or shape you want. You will need bubble-pack-lined envelopes (they are coated with paper, both white and brown manila, or plastic), a pencil, ruler, scissors, packing tape, paper fasteners to attach handles, and stickers or self-adhesive plastic business-card sleeves and business cards (below).

1. First make the body of the purse by cutting a long rectangle of bubble-pack-lined envelope (the one at top right was 12 by 5 1/2 inches). Fold the rectangle, bubble side in, so the sides will be the same height, leaving 1 1/2 inches or so at the bottom for the base.

2. For the purse, we cut a strip of envelope long enough to serve as both the handle and both sides of the body, and then taped it in place. The handle is tapered at the top for easy gripping by small hands.

3. Adorn the purse with stickers, or attach a plastic sleeve so that you can slip different color cards in and out to suit your mood.

Duct-Tape Accessories
You will need duct tape in a variety of colors, scissors, self-adhesive Velcro, and pinking shears.

1. Create duct tape "fabric" by sticking strips of tape, in any colors you like, sticky sides together so that half of the width of the tape overlaps. Continue to add tape in this overlapping fashion until you have a sheet the size you want. Fold over the remaining flaps to finish the sheet.

2.Trim the edges of the fabric with a pair of scissors to make them even. For decorative edges, trim them with pinking shears.

3. Fold the fabric into the shape you want (this will be a wallet), and duct-tape the edges closed. Attach Velcro where needed to create a clasp.

4. Fasten the Velcro. Try experimenting with different colors and folded shapes, such as the mini folder for keeping stickers, at the top.
