I washed, rinsed swung it by the tail round and round and left it to dry. I'm very pleased with the results - it's a pale wheat colour with stains of gold and Rosy copper. I wound it into two centre pull balls and then got out the old McMorran balance. 340m per 100g according to my calculations - between the two balls I apparently have 640 m. There are 1.09 metres per yard so a little kitchen math says...duh 699.91 yards. So close but cutting it too close I fear.
There's nothing like knitting with your own hand spun and although I've knitted a scarf from hand spun - I've yet to make a garment with my own stuff. The best part is that if you need more - you just dip into the roving bag and voila, problem solved. If there isn't enough roving then as long as you're close - there's always a nice vest.
