So I decided to make my own list of gifts--for $15 or less.
Bananagrams, $14.95 - Kind of a cross between Scrabble and Boggle, this is a high-speed crossword game that's played on the tabletop instead of on a board. You can buy it online by following the link, but if you don't want to pay shipping they also sell it at Barnes & Noble and other stores.
Topsy Turvy Tomato Planter, $11.99 - I'm not usually a big advocate of the "As Seen on TV" line of products, but I'll give the thumbs up to anything that provides a way to grow fresh, organic produce at home year-round. From Collections Etc.
Butter Soft Acrylic Muffler, $14.95 - Scarves have come into their own in the last few years. Not only are they warm, they're a stylish and easy way to dress up an outfit, hide a slightly too-low-cut neckline, or add color to a bland clothing choice. These scarves from Wrapables come in some beautiful colors, but there are a ton of stores that carry these in every color and pattern imaginable, from five to a hundred dollars.
Scrabble Tile Pendant, $4.95 - Made from a recycled Scrabble tile decorated with an image and coated in resin. These are a beautiful piece of recycled art and can be found on Etsy in any design imaginable. I'm a fan of this one from Etsy seller wickedlymodpendants.
I Am Not a Paper Cup, $15.19 - The worst thing about travel mugs is that they're almost impossible to drink from without spilling, and they just don't have the je ne sais quoi of the paper coffeeshop to-go mug. This mug is made of ceramic with a silicone lid. It looks like a disposable cup, but it's permanent, insulated, and dishwasher safe. Currently on sale at Target.
