I always check, too, to see if they are cutting width of fabric or length of fabric. Many patterns call for length of fabric when cutting borders and sashings. I have found, too, that many patterns have figured a bit extra fabric in tneir requirements. However, as I usually try to keep things simple, if a pattern calls for less than a full yard, I will round up, for example, if it calls for 2-3/4 yds, I will just buy 3 yds. I figure any extra will either get sent to my sister who makes potholders or will go into my applique fabric stash.
