For the most part I just buy a yard, cause I like to mix up my fabrics for a scrappy look, but those ones that shout at me I buy at least 3 yrds, The ones that scream at me I will buy 4 or 5 cause I just might use it in more than one project. Take into consideration the ones that look like good border fabric and buy accordingly.
Where are you, it just says middle of Oklahoma? I am west of Enid.
