Felt and linen are great materials to choose when you want to put together an easy DIY device cozy. Felt is soft and it's not difficult to sew, so creating your own cozies and cases for your tech devices becomes a lot less problematic if you're not an expert sewer. Once you've completed your cozy, don't be afraid to decorate it, just like Geninne did with hers.
Geninne's DIY Linen iPad Cozy
Geninne used linen to make her iPad sleeve, and it was quickly completed in less than a day. What really sets it apart is that it was decorated using her hand-carved stamps and pigment ink pads. She set the ink with a very hot iron, but this method is only good for something that won't be washed very often. Otherwise, she'd use ink pads specifically made for fabric. If you want to create your own stamps, check out her tutorial over here. Otherwise you can check out what's available on Etsy. The easiest way to try this is to use a large rubber eraser and get cracking.
Sah-Rah's IKEA Hacked iPad Cozy
This iPad cozy costs less than $2 to put together, and all you'll need to finish this is a scarf and two IKEA Nedda chair pads (99¢). There's not a lot of sewing involved, so anyone can finish this without too many problems. In the worst case scenario, you'll just have to start over and spend another 99¢.
