I found this ripple-along through Craftzine about a week ago. I'd never done a ripple before, so I borrowed a book and found out how.
Best. Thing. Ever.
So now I'm making this HUGE ripple blanket. I'm not very fast at it (probably because it's so long), but you'll get pics soon enough. As soon as I can work out the piccy... thing.
I, too, used the random stripe generator. HOURS of fun, just with that tool.
This is gonna rule.
