Thanks All, Looks like I have the correct colours for piecing. And from a few, it looks like when I decide on a colour scheme, I purchase the needed threads for the quilting part. I also noted that some of you use a different colour for the backing. All this seems fairly straight forward. I just need to plan what is needed on my next quilt.
I now see why some of the companies that sell kits suggest a particular backing, and also the thread colours.
