Technical The upholstery thread to end all threads

The cotton if stuffed correctly will make a very full rounded looking pleat
I always use 1/2” scrim foam and I don’t glue the vinyl to the scrim
I just sew it
Wider pleats come out a little flat though
Here’s some of the tuck pleated panels that are in my coupe

 

im cutting on the black line and sewing the yellow. 2 1/2" wide pleat to start. finishing with 2" wide after sewn back together.

f-head, the material shop i have been visiting said the 1/4" scrim is for the door panels and the 1/2" is for seats. 1/4" so the door handles clear

 

I still use 1/2” scrim on the door panels
Haven’t had any problem on handle clearance
1/4” just looks too flat to me

 

ill give the 1/2" a try for the door panel if the cotton does not work out. im interested to see how the cotton stayes inside the pleats when I cut for the handles to attach

 

why does the thread seem to split as it's going through the needle into the fabric?

 

Needle might be worn out
The thread can wear the hole in the needle causing part of the thread to catch on the needle
Otherwise don’t know
