I have a PQ1500s and the first thing I would try would be to switch to a quarter inch presser foot rather than the walking foot and also lower the pressure on the presser foot. On the PQ1500s you turn the knob that's on the top of the machine, the needle in the slot on the face will go up as the pressure is lessened.

When sewing square rows together, the row on the top should have the seam allowances facing the foot not away from the foot. I know it is tempting to put the top seam allowances away from the foot but that will push the top row further and further along. I use a straight pin to hold the seam allowance as the foot comes to it ( so the foot doesn't catch it) and this method will lock the intersection against the bottom seam allowance going in the opposite direction on the bottom row.

I learned from a expert designer dress seamstress, she use to sew for designers for fashion week in NY. She said to hold the top piece of the fabric up until it goes under the foot to keep the feed even. It works great when sewing strips. Also fabric basting glue is the used by the gallons in the designer houses.

I'm a pinner! Try pinning, using thin pins, removing them just before you get to them. Also, see if you can reduce the pressure on your presser foot. Might need to get out your manual!

Using a bit longer stitch length may help too.l

This video helped me a lot with piecing. Also, try reducing your pressure on the presser foot if the problem continues after changing to a regular foot from the walking foot.

I agree with everything said here. The only thing I would add, is consider a new needle, and use a single-hole stitch plate on the machine. I recently had a problem sewing side seams on a blouse, the result was irregular and messy looking, and sure enough I had my 9mm hole stitch plate on. I changed it to the single hole plate, and put in a fresh needle and problem solved.

I never use a walking foot, they always mess up my stitching.

Take off the walking foot. it is moving the fabric as though you have many layers, including batting. DON'T MESS WITH YOUR TENSION. This is not your problem. I like the dot of glue too, I have used that in piecing curves. I think you will find that a regular foot will solve your problem,....let us know. Best wishes

I've found that if I pin the ends, I can ease them to fit if needed. Also, I've found that when I put the length of grain with the width of grain, the width stretches and the length doesn't.
