OMG - what a fabulous thread!!!
Well, 10% automatically goes to purchase Godiva chocolate, as it's a nice addition to yarn at any time of day!
Now, let's see .... I would buy my current favorite stuff, Debbie Bliss Cashmerino, mainly in Baby, DK and worsted weights. I know it has some microfiber (read: plastic!) stuff in it, but it knits up so beautifully that I haven't been able to resist.
I would spend about $150 easy in Jeff's eBay store on my beloved Addis.
I would buy $100 worth of Malabrigo yarn.
I would purchase some good ol' fashioned, practical wool from EZ's site, along with a book or two.
PS. These fantasies are almost too much to bear!!
