Crochet Toadstool Sweater Keychain Pattern
Looking for a quick and cute crochet project? This crochet toadstool sweater keychain pattern is the perfect little project for using up yarn scraps and getting into the Fall mood.
It’s fun to make and adds a cosy handmade touch to your keys, handbag or backpack.

If you’re anything like me and struggle with gauge and attention span when it comes to making clothing then this pattern is for you. It can be whipped up in a jiffy and no gauge swatch required.
The only slightly tricky part of this project is the toadstool applique and only because it’s so small. Take your time with it and I recommend using a sharp needle when adding the ‘spots’ as it makes it easier to go through the stitches.

About the Pattern
This toadstool sweater keychain pattern is worked from the top down with the sleeves and neckline added at the end.
We will be using both half double crochet stitches and single crochet stitches to make the sweater with the tails from the neckline being used to attach the keychain.
The toadstool is made separately and glued in place. However, I recommend sewing it on if the keychain will be within reach of small children.
Recommended Yarn
I used Paintbox Yarns Cotton DK with a 2.5mm hook for my toadstool sweater which gives a cute keychain size.
I love using cotton for projects like this as it’s durable, holds its shape well and is easy to care for.
