If you're dragging your feet on starting a get-fit-for-the-summer exercise routine, maybe this is just the push you need. Take your tunes with you on the road or treadmill with this DIY cell phone arm band made using a plastic place mat and a pair of hair bands. The arm band can be customized to fit even the tallest and smallest cell phone or music player, all without any sewing. Hurrah!
Marta from 2nd Funniest Thing has found a new love for running. Looking forward to a big race, "La Cursa de El Corte Inglés" in Barcelona, she decided to put together a cell phone running arm band case, and luckily for all of us, she shared the tutorial on Las Manualidades (it's kind of like a Spanish-language Instructables).
It couldn't be any easier to do. Basically, you trace around your cell phone on a plastic place mat before gluing it into a pocket and attaching a couple of hair elastics. You can find the full tutorial and more photos here.
Also, if you've got a spare tube sock (perhaps it's matching pair missing after laundry day), you can construct a sock workout armband for your mobile device without any measuring. Just note, this armband isn't as secure as the placemat version above.
