Interestingly, being cold sheep does not actually seem to have saved me a lot of money. The money that was previously being spent on yarn simply gets diverted into pattern acquisition. And not just your average pattern acquisition, but fairly expensive, vintage British patterns. My relationship with pdf reproductions of vintage patterns is fraught with tension - I like that they provide access to rare patterns, but I hate having to search around them when looking for originals, and am also leery of the copyright issues involved.
Bestway, Sun-Glo, and Stitchcraft are my favorites - all of which are on the pricier end of the spectrum, of course. I love Stitchcraft in particular because of the adverts, for wonderful things like Potato Pete's Recipe Book or Bunco's Toilet Paper ("We ask your indulgence if your retailer is temporarily out of stock").
Material culture is fantastic, and as a medievalist, it is not something I'm used to possessing, so I have been - and still am - willing to spend ridiculous amounts in order to own original vintage patterns. I just can't allow myself to spend time on Ebay and Webs within the same month.
