I'm piecing on my featherweight right now, and suddenly it's skipping stitches. It ONLY happens right after a seam. Skips 5-6 stitches, then sews just fine until I hit another seam. It didn't start skipping until I started piecing rows together, but it did fine piecing blocks into rows. The seams aren't any thicker piecing the rows than they were with the blocks.
Here's what I have done to fix it:
Completely re-threaded, top thread and bobbin, wound a new bobbin as well. Yes, I am threading the needle right to left.
Cleaned and oiled everything, taking out the needle plate. Yes, the "finger" on the bobbin casing is in the right spot in the slot of the needle plate.
Replaced the needle, and yes, it's put in correctly with the flat side to the left. It's a 90/14, if that makes a difference?
I have increased and decreased the presser foot pressure.
My tension appears to be perfect, you know, when it's not skipping.
Any other ideas?
Thanks in advance!
