I'm using elastic thread in the bobbin and I've tried loosely and tightly winding the bobbin, but nothing seems to be working. When I put the bobbin thread in the case, it's too tight tension wise so I tried not putting it through the tension in the bobbin case.
When I start doing a straight stitch the needle thread keeps getting caught around the bobbin/bobbin case? Help!
Nearly the same problem. Do you think loosening the screws on the side of the bobbin case will do the trick? Mine will go through, but stretches the elastic before it gets sewed, causing the elastic to be too tense when it's in the fabric. I'm using a Pfaff Select 1548.
I had a problem with my Pfaff 7570. First, I loosened the bobbin tension quite a lot. Second, I lengthened the stitch to 4.5. Lastly, as
I was sewing. I gently helped pull the fabric as the machine sewed.

Not sure if this works on all machines, but I have used this method on many different models. You should not have to adjust the tension on the bobbin or the top thread. Wind the elastic on the bobbin by hand, not stretched as you wind it. Just normal, then try a test piece. The only thing that you should adjust is the stitch length if needed. The bobbin tension is a very tricky thing to meddle with. Hope this helps.
Have you wound the bobbin with the shiring under tension? you need the shirring elastic to be stretched somewhat as it goes onto the bobbin so that when stitched out, it relaxes and pulls the fabric up.
And yes, usually you need to tighten up the bobbin tension also to stretch the elastic some more.
The Ellure has a horizonal drop in bobbin so you will need to access this to adjust the tension. This may require unscrewing the two screws holding down the needle plate (metal flat plate you sew over). Take this off and now you'll see the bobbin holder area clearly. Look where the tension spring is, the little groove you pull the thread into when threading up. Is there a small dial just near this, about 7mm across? it will have a groove in the top and hopefully a + and - marking.
IMPORTANT: carefully make a note of where it is set now. Take a picture or write a little diagram down so you can get it back to normal setting. Use your little accessory screwdriver and carefully turn it one click to +, then test sew. YOu may need to turn it up 3 clicks to get the elastic stretched enough. Just make sure you know where to set the dial back to when you are done.
Also, remember you won't be able to shir heavy fabric, just light weight cottons work best.
I find that stitching lots of straight lines of shirring like you see tube bodice sundresses made in ready to wear is very hard, factories will have a machine that sews 20 rows at once. And getting enough gathers is trial and error with a domestic sewing machine.
Here's how I do it. Turn down top selvage edge of the fabric width you want to gather, turn down about 10mm and straight stitch around. Now on the wrong side with a sewing marker pen rule lines down from here across the fabric width spaced 1 cm apart. Now lie shirring elastic on these lines and stitch over it with a narrow zig zag stitch making sure not to catch the elastic with the needle. Start each sitching seam one cm from the raw edge of the fabric and finish the seam the same way.
Now I pull the elastic up from each side pulling all of them evenly until I"ve got it gathered enough. Now place right sides together and stitch the fabric into a tube catching the elastic ends in and securing them.
you are doing it wrong, thread the machine top and bottom as normal, shirring elastic on your lap, select a small zig zag or pattern, sew and as you sew pull the shirring elastic taught, mif you wind the shirring elastic on the bobbin you will mess the tensions up.
