The Ewok Village flower vase is one of the fun and simple Star Wars projects detailed in Bonnie Burton's "The Star Wars Craft Book." And at $10.50 or so for supplies, you're not exactly going to break the bank on this one.
The glass jar from your recycle bin and the twigs are free. White yarn or string won't cost you more than $4; a quarter yard of brown felt will run you $2; beige and gray felt squares cost about $1 each; a packet of pipe cleaners goes for about $2; and googly eyes are $1.50 or so.
If you don't have a glue gun, get one. A gun and glue sticks will cost around $12 total.
