I cast on 3st on the mainbed and 3 sts on the ribber, and knit tubular for about 23-24". I hadn't like the first few colours that came up so as I needed only about 22", I thought I could just cut off the first inch. However, when I fed the (6mm) elastic through, it stretched width wise and lost length! I had to put it back on and knit another 4". In total, 580 rows on the counter!
To embellish it, I knit two 5 petal flowers from Carl Boyd. The first one I did at T5, and the second one at T4 to make it a little bit smaller. I crocheted the tails into a loop around the band, so although it's not removable, it can be repositioned if she wants to cover up another colour in the band. I was not terribly thrilled with the colours that came up, but it was on a cone so I couldn't take from the other end without re-winding it. I thought at first I'd do a couple, so they would be in a bunch, but it came out big!
For fun, I slipped it over the band of the tam! It could also be wrapped around the wrist for a bracelet, or around the hair for a scrunchie.The flower is a little tedious to sew in all the ends and steam it (and it still curled a fair bit, being only 73% superwash wool), and I'd like to find some other ideas...I'm thinking a short row flower, knit sideways...
In all, this weighed 14grams, which included the elastic!
