My granny taught me crochet when I was 6 or 7 years old.  I made a few things for my dollies but I never had a pattern and had to make it up as I went using the stitches I knew.  I never learned the names of any of the stitches or how to read patterns - even if I had it wouldn't have helped much because granny was Polish.
I stopped doing crochet when I reached my teens as it just wasn't cool way back then.  I hadn't touched a crochet hook for some decades. 
Since taking up loom knitting (because I can't knit and never could), I've been looking for interesting designs to try.  My curiosity into crochet was aroused by a beautiful crochet patterns which can be found on Ravelry.  As I already had some yarn laying about, I thought I'd have a go at a hat pattern I really like.  Amazingly I've remembered how to do the crochet and all I needed to do was look up definitions of the stitches so I could follow a pattern!  Yay!  I can do it!  Here is my very first ever piece of crochet from a pattern.

I made it up using some aran weight wool I have.  I'm so proud!  I will be making up the whole thing in better yarn (when it arrives) as one of my 52 projects challenge.

I wish I'd had a proper go sooner - it's like getting on a bike :-)
