I've actually had these on my mind heaps lately. Not buying them, but making them. (Well...sweet talkin' the good woman into doing it)
I'd slightly re-design them, perhaps even make custom covers. They're so simple in both design and concept so making the patterns would be a breeze.
Couple of questions for those that own one (or several)
Are they lined with anything, or just a single layer of canvas?
Are they super simple to chuck on in a hurry, or do the magnets & velcro make it a little fiddley?
What do you particularly like / dislike about them?
Just trying to guage things atm
cheers
