As yu can see, I have tacked the batting to the felt.
Then using safety pins, I pinned the lining to the batting/felt layer.
Using over stitch I stitched all the layers together - folding the lining in as I went.
I stitched the base to the body of the cosy.
Next step, stitch up the main body.
At the moment the cosy is quite loose.
This will change as I begin to embroider it.
It will shrink as I go. I will need to make sure it is evenly covered so the cosy is not distorted.
I'm not sure if I can do this on the plane, so it is packed into my luggage.
I will post updates.
