Help! Sewing on bleached muslin
I bought 120" wide 100% cotton bleached muslin at Joannes. It has a nice feel and is medium weight. The problem is, my machine makes a horrible racket when I try to sew it. Sounds like it's trying to hammer through the fabric. I'm only sewing on two layers. I stop and put in other 100% cottons, and it sews smooth as silk. Has anyone else had this problem? I bought it to make Cathredral Windows. Making the "packets" on the machine (or trying to) and sewing the "window panes" by hand.
Any insight or suggestions will be greatly appreciated.
