The pattern on the cuff of these gloves is adapted from Co Spinhoven's Celtic Charted Designs by Dover books. You can buy this book new for under $5 and it is a great addition to any colorwork library. I'd estimate over 90% of the charts in the book would have really long floats in stranded color knitting but it is full of inspiring designs.
I recently saw a wonderful photo gallery of crocheted colorwork on Ravelry. Up until then I didn't even know you could do colorwork like that with crochet. HERE is a link showing some of the tapestry crochet from Finland - aren't those sweaters the women are wearing just gorgeous? Photos like that might be enough to get me to learn to crochet.
