Thanks I'll go to a sewing store tomorrow and try to get some!

Hi Everyone! I just recently started my adventure learning my way around an Industrial Sewing Machine. I have a Juki 1541S. I finally thought I got my tension and timing correct, but my stitching isn't secure. When I backstitch, sometimes the top thread shows through and often my stitching can be pulled apart even after I backstitch. Or I'll pull the bobbin thread to test the stitch and a loop of top thread will appear. Any suggestions. Ok, last question. I sew lightweight leather mostly in layers. 3-5 oz, rarely do I sew veg tan together. The needles that came with my machine look gigantic. Groz-beckert 135x17 DPx17, 2 nm 160/23 R. Is this the correct size recommend for my material? I'm also using V69 on bottom and V92 on top. Someone mentioned that I should try lighter thread as the bobbin to help with tension. Is this right in my assumption to do this. Thank you! Leah
