All the iSockit cases can be found at Blythe Kings shop. Blythe King is a self taught seamstress that introduced the iSockit line in 2005. She uses vintage fabrics to create her awesome cases. All of the iSockit cases are handmade and tailored by her.
These are so unique! I wish I had use for on of her computer cases, but I never seem to shut my laptop!
