I've heard of a "walking" foot (other names as well) for use with machine quilting to prevent the back from wrinkling. Haven't found one in my area yet....bet they are a pretty penny as well. (Only guessing.)
I've seen quilting thread...so what you are saying, Sorcha, is that bees wax isn't necessary if that type thread is used.
I'll probably get everything done and freeze when it comes to the actual quilting! LOL
And I just thought of another question....What colour quilting thread? My fabrics are primarily blue (navy/royal) with some tans and creams mixed in...is it preferable (more traditional?) to use a colour thread that blends in or to use a "natural" or even white thread for contrast?
