I have always been a 'Textile addict' !
I love textiles- I seldom limit myself to only one *type* of fabrics- I make sure the fabrics I am going to use will 'play well together' but beyond that I use what pleases me at the moment- for the current project- have sold some fabulous quilts that contained wools, silks, velvets, cottons, flannel, corduroy, denim * yup- in the same quilt* it is kind of a shame - you miss out on so much when you have it in your head you can only use 100% cotton for a quilt- there are fabulous, beautiful fabrics from all over the world to play with, experiment with and enjoy.
