Now that every last American is carrying an iPhone (we may be exaggerating slightly), there is never a lack of cool iPhone cases in the stores. But if you really can’t find the right one or just enjoy embracing the DIY spirit, Korean design firm Connect Design have a cute way to make your own. Their DIY iPhone NeoCase is a flexible case featuring a cross-stitching grid design so you can make it look however you like.

The Connect Design team has worked up a number of cute and geeky patterns for you to use if you need them, or you can make up your own design. You can even embellish with things like beads and ribbons…if that’s your thing.

It looks like it would be pretty difficult to cross stitch anything on the case thanks to its shape, but apparently it can be done. The patterns on the site range from holiday motifs to Nintendo characters to kitty cats to all sorts of other adorable nerd stuff. Each kit will cost you $18 and fits iPhone 4 and 4S.
