..... now I am knitting away happily with this ring & there is no mark on my finger. What a great idea - thanks to Lynette - if only she applies this level of thinking to her Economics!
If any of you are interested in making one of these rings - it's easy. I use sock yarn & my gauge is 9 sts per in & I measure around my finger (not too tightly) - cast on 20 sts using 2.5mm dpns, join the round & knit till the required height, cast off. That's it - a knitted ring. I am so happy with this that I am knitting more in different colors. This ring not only solve my problem but it will be fashionable to wear (just in case I forget to take it off). I LOVE IT !
