I’ve been sewing some silver glitter to leather today, and it took me a while to get going. I hadn’t used these particular materials and threads together before, and found as I did the little sample I always do, I had real problems with the top silver metallic looping and being fed below to the backside of the work with a crazy result; and that every few stitches if they weren’t looping, there were occasional skipped stitches. Pulling out stitching with leather of course leaves holes, so when you re-do it you need to have the same stitch length to re-use those holes, going slowly until you’re in new territory.
I need to say, too, that my machine here in Montevideo is a very basic domestic Bernina – a great little machine, but there’s absolutely nothing computerised in it, and there probably are newer models that easily handle this kind of thing with the flick of a button or two.
I noticed that every now and then there was a skipped stitch (upper left) Now I really wanted to use this silver thread and so decided I’d just try this little sewing job of 75cm, I’d take my foot off the pedal altogether and just turn the drive wheel manually. While doing this slow motion thing I I saw the springy thread loop under the needle point and come up round behind the needle so the next up-down movement would make the thread loop and bunch underneath and I realised this was probably causing the thread to skip occasionally. I finished the line of stitching around the edge of the leather, having the time to keep the several potential trouble spots under supervision. These are highlighted in the pics below. I know I could use a much larger needle, like a jeans topstitching needle, or there’s probably a leather needle I don’t have, but I did not want to make large holes in the leather, so that’s a trade-off I faced and decided to keep the needle as was.
(UL) Skipped stiches; (LL) twists/loops may occur at the feed into the tension discs; (Centre) twists/loops may occur at the top of the overhead arm; and (Right) thread may twist/loop round the back of the needle.
Sometimes I wonder why I do the things I do – and you might, too. More on the overall little project some other time.
