I've recently been doing two things that I never thought I would: Crocheting dishcloths.
I've never had the patience to work in fine yarns and I associate crocheting in thicker yarns as ugly and old-fashioned.  Very 70s.  In a non-cool way.  As for dishcloths - why would anyone want to put their time and effort into creating a rag to wipe up dirt?
Then someone sent me a knitted dishcloth in a swap.  It was made out of the most butt-ugly white, orange and brown variegated yarn I had ever seen.  I tossed it to one side on the kitchen bench and forgot about it.
Several weeks later I spilt coffee on the bench and was casting wildly around for something to wipe the mess up with.  I grabbed the dishcloth and used it to absorb the excess coffee. It was really effective.  It was soft and useful and absorbent.  And it rinsed out easily in the sink.  I tossed it in the washing machine with the towels and it came up good as new.
A light-bulb went off in my head.
I grabbed an odd ball of ugly cotton yarn from my stash and knitted up a square in moss stitch.  The knitting was fine but the colours looked terrible.  As a lovely absorbent dishcloth it worked perfectly.  Unfortunately, however, I hated the knitting; it was boring and took forever and the cotton yarn was stiff on my fingers.
For some reason a few weeks later I was playing about with some of that yarn and a crochet hook.  I've never really learnt how to crochet but I can do a basic chain and sc stitch.  I looked down at my handwork and discovered that the ugly yarn actually looked a hell of a lot better crocheted up than knitted.  And crocheting was certainly faster than knitting.  I wasn't very good doing the turning chains at the end of each row but who cared if the edge of my dishcloth was a bit wonky?  It was just going to hide in a draw and come out to wipe up coffee stains.  As I finished my square, I had a brainwave.  What if I did a final sc row around the entire perimeter of the square?  That would neaten things up.
Two dishcloths later I had the idea of finishing my final sc circuit with a chain of about 10 stitches that could be formed into a simple ring tag, making it easy to hang my dishcloth on a hook in the kitchen.
And that was it.  I had designed the perfect dishcloth for me.  One that was easy and fast and fun and could be done while concentrating on an enthrawling movie or tv show.
I bought a few bags of cheap cotton yarn "odds and ends" on sale.  I adjust my dishcloth size to suit the yarn available.  Sometimes I do the final circuit in a different yarn.  Sometimes I do several circuits.  Whatever I feel like.
I still haven't perfected doing a neat turning chain, despite hours pouring over diagrams and instructions in "Crocheting for Dummies".  But I am getting better and better at fudging and covering my mistakes.  And I relax knowing the in the worst case scenario, it will still be fine for wiping up the kitchen floor.
