I know we all see items in stores or online that we could make for cheaper... Frankly, sometimes I'd rather just buy the store version (lazy?), but with some things it's fun to have a personal touch or choose my own colors. So not that I ever get around to all my grand ideas, but here are a few recents I've bookmarked to make at home:
Urban Outfitters thread wrap bangle bracelets - $19.99Make at home with thread and a cheap-o set of bangles (I have a set that's tarnishing and needs to be revamped anyway); you can get these at places like Forever 21 (example set for $5.80, or thinner ones for $2.80).
Pottery Barn homescent candle pot - $12.99 eachMake at home with $2.99 Ikea candles and alphabet stamps, which I happen to have on hand (similar).
Faux bois lamp shade via Amazon - $99.91Make at home version could be rigged up with an Ikea shade ($10) and this gift wrap ($7.49) from the Container Store.
