My mum used to be considered a good knitter (before the bifocals) of the complex cabling variety, but she wouldn't do Fair Isle.
Me...I can't keep an even tension for a single line, never mind choose how many stitches to the inch.
My Mum taught me to knit when I was about 5. Hands are more agile then and can learn to do these things....
I'm a fiberholic--have bags of fleeces ready to spin and dye, and boxes of yarns. Eoghan the cat loves to knit too, but not in a helpful way ;-) Elaine
