Black sheep, black sheep, have you any wool?

So, I got a new laptop and I need a sleeve for it. And, naturally, I started wondering about making one. It turns out that it didn’t take very long (all of about 12 seconds of Googling) to discover that wool felt has become very popular in the last couple of years. And with good reason, if you ask me — this is some fantastic stuff! And it’s become very popular for laptop and other gadget sleeves.
