I am seriously considering jumping into Fair Isle and Intarsia and have been wondering if I should be using bobbins. As many here know, I love to collect vintage knitting accessories (not needles, however) and I've posted a photo of my favourite bobbins. The largest are from Canada and made by Perfecto; they measure 4 cms. The 2 at the left are from the UK, are unmarked and measure 12.5 cms. The remainder (and I have lots of these) are labeled Yarn Bob'n and come from the US (Chicago). That's their box with the original price sticker of .79 cents.
