Pressure adjustment
 

I haven't seen much info about it. On many machines there is a knob or screw on the top of the machine above the needle that can change the pressure exerted on the presser foot.

Beyond that, I don't know when to adjust it, how much to adjust it, or which way (less or more) to adjust it.

Clues? Help?

I'll be watching this, one of my older machines needs something, I think the pressure adjusted.

what brand is your machine?? do you have a manual at all? you may find one online if no one is able to help here.

My manual has fabrics and a color-coordinated chart listed. The colors are printed on both the pressure knob and the feed dogs knob, which raise or lower incrementally depending on what kind of fabrics/sewing I'm doing. I'm familiar enough with my machine now that I don't need to consult my manual anymore to know how to adjust the machine.

When I experienced skipped stitches zigzagging the multiple thicknesses of fabric and batting for my Bailey Island bag, I tried increasing the presser foot pressure, and it made a big difference. I don't remember needing to adjust the pressure for anything else.

Daffy

My Brother machine also has a color coordinated chart both on the indicator for the presser foot and on the feed dogs adjustment to sort of guide you along.

I adjust mine to lightest possible pressure for FMQ, of course. Other than that, I sort of play with it when my stitches look off. As mentioned earlier, changing the pressure when sewing extra thick things tends to make nicer stitches.

I've never changed the pressure - haven't seen the need for it. Guess I will have to look that up in my manual and find out when to make the change.

Even my old vintage machine I can adjust the pressure. It at the top of the machine and screws down to add more pressure. It took me awhile to figure out what that screw did!!
