I started a little jacket in Jet for Marcus a while ago from this book:
I'm making the all one colour version of the jacket. As usual, I photocopied the instructions and circled the third size, being size 4. It was only after I couldn't find the photocopy that I pulled the book out and discovered the ultimate stuff up.
The third size isn't a size 4. I assumed the sizes were 2-3-4 etc, but they're not.
*sigh* At least Marcus will be warm in two years time.
