I started taking my fourth quilting class and our instructor mentioned two things that I had never thought about.
#1 - Always sew with the same type thread as your material. ie cotton to cotton. He said that if you use polyester on cotton it will eventually wear out the seam by sawing thru the cotton material, expecially if you are making a wall hanging.
#2 - If you prewash one fabric for a quilt you must prewash all fabrics - due to shrinkage when you wash the finished quilt.
I am new to quilting but am wondering are there any other hints out there that we newbee's should be aware of?
