rein, you may certainly PM me. glad to be of assistance.
not quite sure what you mean about "Did you have anything between the muslin and the scrap strips?" the strips of scrap fabric are sewn to a muslin base. that's string piecing. we discussed in another thread awhile back. it is sort of like paper piecing only the muslin stays put as the foundation.
this is absolutely the fastest quilt i have ever made. i literally finished to the point of taking the picture in one day. about 6 hours. that is part of the fun. satisfies my need for immediate gratification. ;-)
