I just wanted to let remind y'all that I only had thirty three strips ... so, when you are using 40 strips, you will be doing the joining the top to the bottom a few more times.
The reason to cut off selvedges is: The fabric is more tightly woven in that area, and for some reason, it continues to shrink no matter how many times it is washed .... it really can and will affect the finished project.
I will come back when I have better quilts to show off .... I am going to experiment <g> <wave>
