i agree that scrappy is made from many different fabrics and their placement is random.
i do believe quilt makers can go and buy fabric to make these kinds of quilts though.
if their artistic voice is to make scrappy quilts i don't believe they should have to buy fabric to make others projects in order to gather the necessary scraps to finally make the scrappy quilt that they really want.
scrappy artists buy FQs because until recently that was the smallest piece they could buy - now with all the precuts on the markets its much easier for them to buy what they need.
why should someone's artistic voice not be heard because they haven't acquired enough scraps yet - let them buy fabric and make what they want.
