Threading Machine

I'm new to sewing (although I have used the machine before it has been years. And even then I was just a basic beginner). I have my sewing machine set up and I have a yellow thread on top and a blue thread on the bottom (boppin). Now I have the need in the up position, and I go down one stitch and it hooks with the blue thread then I pull them off to the side. However, when I'm sewing it only sews the top yellow thread and not the bottom stitch. Obviously, I'm doing something wrong but all time I do it, this is what happens. PLEASE HELP. . I was so pleased to find this — Most likely answer is needle size too small for the fabric being sewn or the needle's in backwards. But the bobbin case may not be in correctly, the bobbin may be poorly wound, the machine dirty or in need of oil or misthreaded or. . Or. . I did a series of photos of what happens with any common misthreadings of a sewing machine. They're in pairs; the first pair is from a correctly threaded machine, the rest are from the same machine that I deliberately misthreaded. See if you find a match here — red thread is in the bobbin, blue thread on top: As far as cures: The 10 minute fix for most of what ails most sewing machines: — Dig out the manual. Take all the thread out of/off of the machine. Pull the needleplate and the bobbin case if it's removeable. Clean and oil per the manual's recommendation. Use a brush and vacuum, not compressed air (which blows lint in farther), and real sewing machine oil, not 3-in-1 type oil (it hardens and freezes the machine) nor WD-40 type stuff (it's a solvent, not a lubricant). — Put in a new needle of the correct point style for the fabric you're sewing (ballpoint for knits, sharps for wovens) and the right size for the thickness of fabric (10/70 for shirting weight fabrics, 12/80 for heavy shirtings or light pantsweight. 14/90 for medium to heavy pantsweight, 16/100 for very heavy fabrics. Make sure the needle is in right way around — a needle in backwards will skip stitches or not stitch at all. — Take a good look at the bobbin. If it's lumpy or you spot loops, strip off the thread and rewind. Bobbins should be smoothly and evenly wound. Wind at a slow, steady speed — it helps with tension issues if the thread isn't stretching as it's being wound. — Rethread, with manual in hand. Make sure the presser foot is UP when you thread the top — it opens the top tension so that the thread actually gets in between the tension disk (loops on the bottom, not enough tension on top). — Fetch up the bobbin thread. You need about a 4" tail of thread top and bottom. Run both threads under the presser foot and behind it. — If you've been playing with the top tension, set it to4. If you've been playing with the bobbin tension, let me know and we'll try to rebalance it, but you're likely to have to take it into the shop. Now, each and all time you start to sew a seam, this is how you do it: 1) Place the fabric under the needle, and use the handwheel to lower the needle into the fabric (be sure to turn it the right way. . Seee the manual). 2) Drop the presser foot. 3) Hold the thread tails behind the presser foot with your left hand. 4) Take a couple of stitches 5) Drop the thread tails and sew normally. If this doesn't fix your problems, you may have any thread caught farther in the machine than you can spot. . Doesn't take much for any machines to start pitching a fit. Or you may have accidentally knocked the machine out of time with one of the jams. Bad timing is actually a fairly rare event, often preceeded by broken needles and loud noises, but a good solid jam is another way to throw off the timing. You can check here to see if you think timing is the problem: Or http:// tinyurl. Com/ smtiming (you'll have to paste that back together) but that's generally something that a repair shop needs to adjust. Really good habit to cultivate: Whenever you sit down at the machine for the first time that day, take two minutes and give it a basic cleaning. You'll save $$$ on repair bills and extend the life of the machine.

    My spouse always has me thread the needles. If you do not have one, you require a husband.

    I'll admit that I'm just guessing, here. . . Could one of the thread tension adjustments be way off? Either the one for the top thread (usually controlled by a knob) or the one for the bobbin thread (might be a screwdriver adjustment on the bobbin case). Or perhaps you don't have the bobbin thread running through the case correctly?

    You may have the wrong sized needle and it isn't going down far enough to catch the bottom thread. Try the thumb screw on the needle, loose it, and pull the needle down just a smidge, and using the wheel, see if it goes down far enough to catch the bottom thread. Hold both threads in your left hand, and turn the wheel with your right, and you can tell, if it picks up the bottom thread. You should do that every time you thread the needle anyway, so that both threads are on top of the feed dog.
