Several points:
1.) I was married to a home weaver for a long time and observed these things..
a.) Home woven fabric comes in many tightness of weaves, some loose like burlap, some absolutely tight like linen.
b.) Wool binds together better than cotton. The little spurs in the thread grab each other and bind the fabric together. Like felting.
c.) If the fabric is a twill, don't worry too much about it. Very complex fabric structure.
2.) Pinking rotary cutters... make sure your first cut is right, lot of pressure. You don't get a second chance.
3.) Use wider seams. Then either serge or zigzag to secure those seams. That quilt will never come apart.
