I came across this FANTASTIC BLOG called Melly Sews with the EASIEST patten for shorts. If you're looking for a fun project, sign up for her weekly newsletter, and she'll email you a link to print out the pattern. Not only that pattern, but all of her others, too! Sew simple! <---- sorry, a little sewing humor.
Anywho, visit Melly's page for instructions... It wouldn't be nice of me to copy and paste instructions because simply, I didn't create it. Just a little reminder if you're sewing clothing: REINFORCE THOSE SEEMS PEOPLE. It takes an extra minute, but it's always worth it. The last thing you wanna do is jump around screaming yee-haw while your hoo-hah makes a break for it.
I always leave a 1" seam, and stitch over it twice. Then, I'll fold in the excess fabric, and stitch over that: This keeps the seam clean and free of frays. And remember: If you're making something, even if it's for yourself, put a tag in it! You don't want to end up like I did when someone ripped off my art as their own. This is an AWESOME project and it is simple, simple! Get this: Each pair of shorts, including the cost of fabric and elastic for the waistband.... COST ME A FRIGGIN' $1.99. WIN!!!
