When I began quilting I used poly. My firstroject Iurchased some poly and didn't realise there was different thicknesses and mine was way too thick looking back. Then I began using woll, cotton, Hobbs dream etc because I was told it was the one to use. My last quilt is being done with poly and I realise that for lightness and definition it is so good.
I've come to the conclusion in the last few weeks that I must select for purpose and not be led by others.
