Thread gathering in ball under fabric It is singer futura 150

Be sure to try a brand new needle. Otherwise, it's possible the machine is slightly out of time. Search for "sewing machine timing" or take it for service.

Here are several videos on YouTube that may be able to help you. SINGER FUTURA Threading the Machine Tutorial

You're probably correct. The new Singers are not what they used to be...Singer was bought out a few years ago and many buyers have registered their regrets and disappointment with the new products and service.

Most complaints about sewing machine problems concern thread loops under the fabric, which are usually caused by the upper thread. Your problem is not as common. Generally, when thread problems occur on the top of the fabric, it is a bobbin issue.

Try a brand new needle. Make sure the needle, thread, and fabric are compatible. Also, check that the needle is installed correctly.

All About Needles

Remove the thread from the machine. Check that the machine is clean--no lint, dust bunnies, thread pieces in the bobbin area, stuck in the feed dogs, or under the needleplate.

ALWAYS RAISE the presser foot when threading. Rethread the machine from the beginning. Check that the thread path is correct for the upper thread and that the bobbin case is loaded and threaded properly. Use the same thread for both upper and bobbin.

Most machine standard upper tension is set at the midway point. However, this is just a beginning point. The tension differs from one machine to another and may need adjusting depending on the fabric you are sewing.

Retest your machine.

If loops are still forming on the top of the fabric, then the bobbin tension may be too loose. Try tightening the bobbin tension (only 1/8th of a turn at a time!).

Understanding Thread Tension Threads

Sometimes it is a thread issue. Experiment with different brands of thread. Avoid old or bargain bin threads (the thread in bins at the fabric store are not the best, also Coats & Clark may not work well in your machine). Stick with better quality threads, ie Gutermann, Aurofil, Isocord, etc. Be sure to use the type of thread that is suitable for your project, ie do not use embroidery or cotton thread for sewing garment seams unless you want to be embarrassed when the seams start popping... Polyester used to be the bane of sewing projects but is now used for many items because the quality has improved and, in some cases, surpassed the former favorite cotton. Polyester is light weight but strong. Some machines just do better with one brand of thread over another.

You may also consider testing the machine with different types of fabric to see if it performs better with a particular fabric type or weight.

If it continues to be a problem, perhaps the bobbin case is damaged or malfunctioning. If you cannot find the answer to your problem, you may just need to take it for service.

You need to tighten the upper thread tension so that the thread does not accumulate under the fabric.

bobbin thread is too high pressure or too low pressure on teh top adjustment!

remove bobbin and turn tension screw about 1/8turn left (anticlockwise) check if still grabbing, if so - top thread turn about 1/4 turn (at embroidery ir should do automatically, but sometimes need kick...).

check if it is still grabbing on the bottom, do it grab during straight? zigzag? double zigzag? if do not - setting on the pattern need to be look at. if it tangle as well on these three - need definitely servicing...

follow manual how to adjust.

ANOTHER THING IS TO CHECK THE TENSION OF THE BOBBIN THREAD. MAKE SURE THE THREAD YOU ARE USING IS GOOD THREAD THAT DOESN'T PULL THE COTTON UP AND CAUSE A PUFF BALL ON THE NEEDLE. CHECK THE WAY YOU ARE LOADING THE TOP THREAD. ALWAYS DO THIS WHILE THE FOOT IS UP SO THAT YOU CAN CONTINUOUSLY GIVE TUGS THROUGH EACH OF THE GUIDES. THIS HAS TO BE LITTLE TENSION WITH NO SNAGS.

Normally to gather fabric, you select the regular straight stitch, turn the stitch length up to maximum (4 or 5 usually), and stitch two rows of stitches, one at 10mm from edge and one at 20mm from edge.

Then gather by pulling the bobbin threads (underneath ones) from each end to gather the fabric. If doing lengths of more than 1 metre, then stop, leave long thread tails, and start a fresh length of gathering threads to avoid gathering long lengths of thread which might break on you.

If your machine has a basting stitch it might look like " .___.___.___" on the dial however, I've never been that happy with machine basting for things like attaching slippery fabric to underlining, I've always done it with needle and thread to keep the two layers matching and not stretching/slipping. For example, stitching a piece of chiffon to a underlayer of satin, even pinning carefully, these two fabrics will slip under the machine foot so I'd always do it by hand.

If you have masses of fabric to gather, sometimes what is quicker is doing a large wide zig zag over a length of perle cotton (heavier than thread) at the 15mm seam, don't let the needle pierce the cotton though. Then you can gather the fabric along the perle cotton.

Sewing machine instruction manual often assumes a knowledge of sewing techniques that you may not yet have. I have the Vogue Book of Sewing on my shelf and refer to it often. Or Singer do a good range of sewing books too, its worth investing in a good reference book.

I also love www.patternreview.com, this is such an awesome website for dressmakers/sewing enthusiasts and you will find loads of helpful tips here.

Hope this helps you a little.

Either upper thread is not passing through thread sensor area or sensor is broken.
Second possible reason is that if design is not optimized the sporadic speed change provides thread breakage error even if the thread is not broken physically. Make sure your software is updated to optimize it automatically (Futura main menu->Help->Live Update).

Select in the main Futura menu Help->Machine setup Tutorial, lesson 10b, the balloon shows the proper position of the upper thread inside sensor checked area.
