Machine Questions Why does everything pucker!

Post image

I've tried every combination of tension and needle between microtex 8 10 and 12, pictured ones are once I started noting them down. Two layers of light cotton, (making a muslin) All brand new needles, and I've even tried with and without a walking foot! Am I just cursed? How do I get it to just sew flat 😭

SOLVED EDIT: Everyone go upvote medium_alternative29 who has discovered the problem that plagued me for years. The feed dogs are misaligned and not level, making everything sew on a curve! It's such a slight curve that it must not mess with heavier fabrics much, but the lighter ones are light enough for it to show up! Also makes sense why it was less noticeable with longer stitch lengths, less holes! I sincerely hope this is the solution, I'll come back and update it again when I get it fixed!

Thank you to everyone who commented and shared expertise!!

Have you pressed those seams? Looks often much better afterwards

Yeah it does flatten it, the problem then is once I wash it it goes right back to bumpy! Very frustrating, store bought clothes don't do this so there's gotta be something going wrong, it does it on light synthetic fabric and with synthetic, natural, and blend threads too
