I have completed 2 of these in the past therefore purchased another but from Britian in Stitches (Northumberland)

I was unhappy with at least 3 colours and duly changed them, not all of the instructions are as clear as i would like but it does have a chart to add other names with just enough space to do so.

When starting ensure that you look at the arrows on the middle page, detail of where the pages cross were helpful. You may want to change the colours a magnifiing glass could be use full and try to check the colours in natural day light.
