Re: having trouble with my bobbin thread
Check your tension disks, with your presser foot up, and the tension dial on zero. Sometimes a piece of cotton breaks off between the tension disks and then prevents the disks to work properly. Also make sure when you thread the machine, the thread does go through the disks and over the take up lever. After you threaded the machine, before putting the thread through the eye of the needle, lower the presser foot and while pulling on the thread with your left hand, increase the tension with your right hand. Do it slowly and you should feel in difference in tension. If this is the case, your machine should work fine. Good Luck!

after threading the needle pull about 6" of thread out the back under the press foot
that way the thread is jammed under the foot and is held in place for the next thread
bobbin thread should also be out the back
when you have finished sewing then lift the foot and move the material sewed about 6"" away from the foot before cutting the threads
I suspect that the bobbin thread you are talking about is in fact the top thread that has been pulled under the material, make sure that the top thread is pulled into the tention discs firmly and that there is no fuzz in with the thread, also make sure the top thread is properly threaded and is actually in the take up bar .
Try these suggestions
1. Change needle
2. Rethread the machine--top --make sure to use every thread guide
3. Take the bobbin out --make sure it is inserted correctly into the bobbin
Case, & make sure the bobbin is turned the correct way
4. make sure the thread has not come off the thread take up lever
5. Clean under the needle plate & in the bobbin area for lint or threads
Set the tension on the sewing machine for the weight of the material you want to sew. The tension setting shows in the stitch on the material. Use the chart on the machine that matches types of stitches with suggested material tensions. An example of this is, the stitch to sew jean material is different than the stitch to sew silk.
Take the bobbin and wind the thread around it. Make sure the bobbin is empty and don't fill it too full of thread. A bobbin filled too full won't stay tightly spun.
Thread the string evenly on the bobbin. Move the thread back and forth evenly and in layers that are level. Many Singer sewing machines have a bobbin winder on the top of the sewing machine, and the consistency of how it threads can save you frustration later.
Find the hole on the bobbin that is located near the inside spindle of the bobbin. Take the thread sitting on the sewing machines spool and insert the thread in the hole from inside the bobbin to the outside. Set the threaded bobbin on the spool designated for spinning on the top of the sewing machine for some Singers.
Turn the side drive wheel slowly until the threaded bobbin has a layer or two of thread on it. Push down on the drive peddle and fill the bobbin, but don't thread it to the very edge. If the bobbin is too full the thread will release erratically. Cut the thread from the spool.
Drop the bobbin into the bobbin case under the area where the needle sews the material. Close the case and turn by hand the side wheel drive until the bobbin threads into the sewing machine. You can tell when the bobbin is threaded by the tiny piece of thread that juts out of the bobbin case where the needle goes up and down.
Grab the thread with your fingers and pull it out approximately 4 inches. Your bobbin is now spun and threaded.

Be sure to use the correct thread, advised in your manual and that your bobbin and top threads are not too different or else you will have problems. If, you are using a real thin material, try putting tissue paper under your fabric so that it won't get caught. in the needle hole. Usually matting under the fabric is caused by incorrect threading but I am suspecting your thread itself. If, you don't have a manual, go brother-usa.com and download one for free.
--Some times you may have to use a neelde with a larger eye so that the thread will flow though the needle easier,
-Sometimes the clearance on the bobbin case stop has to be adjusted to allow for thicker thread,
-Be abundantly sure the top thread is through the discs on the top tension and not behind the tension devise, then increase the tension to a tighter position. if there are numbers on the tension, og to 5-8 so tyhat the thread will pull up into the fabric and not form loops under the fabric
-What type of thread are you using, possibly try a thinner thread
-check the bobbin as it spins in the bobbin case and after you have put the thread under the tension spring on the bobbin case, be sure the thread will pull out of the bobbin case relatively easily if not loosen the screw on the bobbin case ( righty-tighty/ lefty-loosey)
if all this fails you had better take it to an industrial sewing machine technician
