Straight Stitches on Knit Fabrics... I'm Skipping No More!

Settings for straight-stitching Jersey/knit fabric
Settings that work for my machine to sew Jersey & Lightweight knit fabrics!
YES!!! I have FINALLY gotten together a successful formula for setting-up my beloved vintage zig-zag Novum sewing machine for stitching on jersey and other lightweight knit fabrics!

These days, since the Hubster bought me my lovely Overlocker (serger) for my birthday back in 2012 I'm usually okay for 95% of construction for T-Shirts and other knit garments. I just whizz them through the 'ol Brother 1034D with a smile on my face and the wind in my hair ;-) LOL! However, in the absence of a *Coverstitch sewing machine in my life I do like to get a straight-stitch effect on my cuffs and hems using my ordinary, regular sewing machine.

See an example below, of the typical problems I used to have with skipped stitches (from way back in 2012 when I sewed up Zoe's FREE vest pattern).
Skipped stitches
Opps - can we say "Skipped stitches?"

Previously, I struggled badly with skipped stitches and tension problems, all of which resulted in nasty, loose, unsecured, badly sewn seams, and pulled, wavy distorted hems :-(. Sooo NOT a good look for your me-made clothing!

My PREVIOUS Solution... 
I had until last night, been able to alleviate some of those problems to get "nearly" okay results by: 
• using a Microtex Sharp 70/10 machine needle (I had tried Universal, Ballpoint, Jersey, & Stretch needles, but counter to universally accepted advice 'Sharps' worked best for me!)
lowering tension on my upper thread (down from my usual 5 to 4), 
• using a medium stitch length (usually 2.5), 
• using a narrow width zig-zag stitch (to "look like" a straight stitch), 
• plus placing pieces of paper underneath the fabric (to aid it's movement through the machine - as it is sandwiched between the presser-foot from above, and by the feed-dogs beneath it). 
 using a super slow speed on the foot-pedal.

NOW, What I Do Instead...

I am now able to do the following to get a straight-stitch on anything from lightweight 100% Viscose knit fabrics, to Cotton/Lycra Jerseys
• using a Stretch 75/11 machine needle,
• lowering tension on my upper thread (down from my usual 5 to 3), 
• using a longer stitch length (increasing from 2.5 to 3.5-4), 
• using a straight stitch
• plus lowering the 'Feed Dogs' to the 'Silk' setting (so the machine "grips" the fabric more gently as it passes underneath the Presser Foot during stitching). 
• using a moderate-to-normal speed on the foot-pedal. 

And, these new-to-me settings don't require me to carefully rip out pieces of paper, or to painstakingly use my tweezers to remove miniscule tufts from the seams ;-) And, the stitching is completed much faster too - bonus!

My Thoughts on What Went Wrong Before Previously...
I'm assuming (and this is just me theorising here) that on my old settings where the 'Feed Dogs' were on the 'Normal' setting; that perhaps the machine was gripping the fabric too tightly? Maybe, that "grip" was causing it to slightly stretch/pull and alternately sometimes allow the jersey fabrics to get stuck just a little bit. Therefore, the irregular movement of the fabric passing under the presser-foot caused missed and skipped/ill-formed stitches. With the 'Silk' setting the grip is less-firm, and I believe that the fabric now moves through evenly and smoothly - thus allowing for a good stitch-formation to occur. I also believe that the reason I previously had to use the Microtex Sharp machine needles was, because the fabric was being stretched under the too-tight grip in some instances, it was effectively overly taut (like a trampoline!) underneath the path of the descending needle. So, the rounded-tip of Ballpoint etc. style machine needles simply "bounced" off of the tight fabric surface - as it was unable to pass through the fabric easily = missed stitches!!!

*Oh, my how I DO covet a Coverstitch machine but with x2 Overlockers, x3 Novums, x2 Brothers, and a Singer hand-crank in my life already I really don't have the space for one *sigh*
