Hi Steemit :-) I made this mushroom, it's not something that I can write a full pattern for as they turn out different every time.
I start by using a magic circle to create the cap and work it out to make a curve. I then use white wool and a needle to create the dots.
For the stalk, I create a magic circle and in the back loop only, work upwards to create a tube. I then work outwards to create the underside of the mushroom.
You should have a go, mushrooms were the first thing that I ever made and I've never looked back :-P
Thanks for looking :-)
