making Kenmore do what it can't,hot rod seats

[Hell Bat]

Home made hot rod upholstery is the prodject; Low $ no $ ,yes I have little idea of what I'm doing,I build all types of cars,but tell now did not try sewing :o
Looking for a trick other then paying $ I don't have for walking foot type machine,I read all the stuff for the most part.
The big prob I have is the yardsale $5 Kenmore 1972,158-14401 really dose sew great tell the feet don't move all the junk I'm trying to sew=it dose sew it fine when its all moving well ,and as soon as it don't move on time NOT CITY and jam.
Ok,I'm sewing heat sealed rolled/ pleating and two layers of vinyl,but the backing on the pleating is to soft for the slipper dogs to grab right and move as they do if only sewing two up 4 vinyl together vinyl.
So reading alot of stuff,and note about tape Buckram?,could this stuff give feet something to grab?or something like it??give some grab to back of sewing,glued on or? .
Here's the part I fine a bit funny,if I sew it all up side down it sews great[vinly top show side down] ,but I can't see were I'm sew that way or hold layers in the right places. The dogs grab show side of vinyl good it seems.
128 thread i'm using is too big?but works on a lot of test?,i'm going get some 92 or 69 and try that,report back later.
[new]I do have a Kenmore walking foot adtachmint now also to play with,was only $11 so in my small piggy bank jar,we'll see.
Thanks

1) Put your post in the general discussion section (not in Green Room) for more people to answer

2) Go to your kitchen and grab some "Freezer Paper".  If you don't have any, go to Publix and get a roll in the aisle with the tin foil and plastic wrap.  It's white paper with wax (plastic??) on one side and regular paper texture on the other.  It's the stuff butchers wrap your meat in if you go to a meat market.  The "paper" side might be rough enough for your feed dogs to grab. Sew right through it and rip it off after the seam is done.  If it doesn't work, then you have paper to wrap your meat in  ;D  I find Freezer Paper makes really good templates as well for small pieces.  Really stable stuff.  Doesn't stretch and the waxed side makes it more durable than most paper.
