No is good! So, I have placed an order for the 135x16x18 needles from Amazon (for convenience). What weight of bonded polyester thread? Where would you purchase?

So, the Juki has been in my possession for 10 years. I have used it probably 40 hours in making covers for gym equipment. Normally, I would use the 69# Nylon with a 135x17x18 needle. It never skipped stitches with my previous material which was thinner. With the newer 1/16" material, it happens. I switched to a 20 size needle before I came onto this forum. It could be that I am not pulling both sides of the seam tight enough before trying to apply the top stitch??? Like I mentioned before, the shop who sold me the vinyl told me that another upholstery professional told them the material was impossible to top stitch. I asked for more info and they had little to say. My O.C.D. tells me that I am missing an adjustment or something. So, if I switched to the 135x16x18 needle, would I need to adjust the timing? Vinyl is the only material that I will ever sew with this machine.

Sorry for the delayed response... My needle is a brand new 135x17 size 20 69# Nylon thread for bobbin and top Material is 1/16" thick. So, 3/16 for the two pieces and a top stitch. The first two photos are of five pieces of material sewn at once 5/16" with no skipped stitches. Top and bottom The third and fourth photo is of a top stitch with only missing once. Top and bottom The fifth photo is of an example of tons of missed stitches with the same setup.

I have had a Juki LU-562 for over 10 years that never skips stitches when top stitching vinyl material. However, I started sewing a thicker version of vinyl like what would be used to reupholster a John Deere tractor seat. The supplier who sold the vinyl to me said that another upholstery shop said the material was impossible to top stitch without skipping stitches. So, what would you tell me to adjust on my machine other than replacing the needle? I like the material and would like to finish using it as I bought three rolls due to the price. Basically, I have no formal training on my machine or how to adjust it. I have tried to review all the Youtube videos on the Juki LU-562/563. Thanks in advance!!!
