There are 4 lovely patterns to choose from - this is the flower pattern and has just 4 rows. I sort of 'winged it' to cover the sides and base of the pebble, using a series of chains (3 or 5) and trebles to create a sort of open lace, decreasing in bits here and there - it just seemed to sort of work, but only AFTER I'd followed her lovely pattern! (I made an additional round of 'all trebles' in between rows of chains/trebles)
I used a 3 mm hook and Puppets Lyric Cotton (8/8) for this one and it worked really well. I'm going to try using some of my hessian string I think and some other yarns from my stash to make some of the other patterns. I was surprised I managed to cover the sides and base using my own 'methods' but I think with a little crochet knowledge on decreasing and shaping, it's possible! You CAN do it - just try it :)
The last image is of the base of the pebble - I think it looks OK for a first attempt :)
When I showed the boys my crochet pebble attempt (rather proudly I must say!) Teenage son said 'Hey, you've wrapped a rock!' - quite a cool response I thought :) 'Little S' was slightly less enthusiastic and said 'What have you done to that pebble??? You've put it in a 'straight jacket'!!' He seemed to think it was rather cruel - as if I'd trapped it forever, inside its crochet-harness!
Anyhow, I love the idea - they would make lovely presents, paper weights, ornaments, etc. and are SO satisfying to do! Off to find some more pebbles now :)
P.S. Here is a link to one site for making a magic adjustable ring which this pattern uses - it's the only one that made sense to me when I was trying to learn it a few months ago :)
