So very kindly Sharon brought in a hook and some yarn in for me. A woman with great patience she got my started crocheting. Teaching me a few stitches and with the rudiments of crochet I was off. Can't tell how satisfying it feels to learn something new and obviously now I have to practise ( & practise).
I'm now groaning under a stack of crocheted flowers having trawled You Tube for instructions ( just a quick google search for 'crochet flower' brought up thousands of results- perhaps not surprisingly). There are so many videos on there with folk demonstrating the making of huge numbers of different crocheted items. Knowing how to use a crochet hook and having learnt a few stitches made it easier to follow the videos, but I'm sure there are instructions on how to get started out there as well.
I'm a convert to crochet although I'll never give up knitting - they actually complement each other nicely. So a big thank you once again to Sharon.
