Wrinkles when sewing curves on vinyl
Hi, can you help me figuring this out? I sew a curve and top stitch it and it creates wrinkles and or dimples. I trimmed all the salvage underneath but it didnt help.

Sorry, none of your pictures are showing up. I can tell you right off the bat that cutting out the selvage (not salvage) won't do any good, in fact it will hurt rather than help. Until I see what you're talking about I can't help you.

Even happens with single top stitch

It looks to me like you're stretching one piece of the vinyl as you're sewing. Are you trying to follow witness marks? Here is what it should look like. I make relief cuts on one side of curved seams to let the fabric overlap before top stitching.
Is one side plain and the other side has sew foam?

Vinyl creeps really bad when you sew it together, especially longer pieces like you are working with. I make the pieces even longer and then cut the whole thing down to the right size when the pieces are all sewn together.

I often catch myself pulling one side(particularly the top) when doing curves. It looks just like the cushions your post, mortizx. When mine does that, and one side comes up a bit short after redoing it, I note the shortage and try to "stretch" the short side just a bit in the long straights to compensate for that shortage. if its a big difference, the pattern may be off.
*edited OFF TOPIC QUESTION, I meant to ask Dan, what brand/pattern vinyl is that you used in the example above?

You can sew two long pieces of vinyl together 20 times, and it will come out different all 20 times. There's no way to predict what will happen. Stretching one side or the other is what caused his original problem.
The vinyl was a scrap from another job, and I don't remember what it is. It is nice looking, isn't it? I'll see if I can figure out where I used it tomorrow. I think it was used in a 46 Ford I did about 1 1/2 years ago.

Dan, it is really nice looking, I would love to cover my old set of Chromcraft chairs in that stuff. Most of the supplies I get are from Woolley Bros cause of convenience, they are right across town but their inventory is not real exotic to say the least.
Back on topic, great point, stretching it is what caused the problems to begin with so mortizx, don't listed to me or you will end up chasing your tail!

I actually figured out what that vinyl is. It is part of the Allante collection from Morbern called Carrara Tan #CR-509. Here's a link to it: CLICK HERE It's available from Miami Corp: MIAMI
Here it is on a '46 Ford door panel.

I can't always have the right answer, 'cuz I'm not always sure how to answer the question. I hope I get the answer right 75% of the time.

What does "witness marks" mean? Do I trim the foam away where the pleat and the flat panel meet? So far I have the welting sewn to the flat panel and it looks great. I can just see that it is going to be a problem to sew the pleated piece to it. Any advice?

Witness marks are marks or notches that allow you to line up two pieces of fabric that you're sewing together.
I would sew the welt to the pleated area first, and sew the flat piece to that. How are you padding the flat area? What kind of material is the panel made out of?
