The thread bumhes up whenever I am sewing
That is called "thread nesting," and several things can cause it. The upper thread enters the bobbin area during sewing, catches the bobbin thread, and as the needle goes up, pulls the stitch tight. Something is catching the upper thread as it goes around. The most common reasons are the bobbin or bobbin case (or both) is improperly inserted; the bobbin is warped (roll it down a flat surface--if it wobbles, it's warped), either the case or the bobbin is not seated evenly, there is a rough spot on the bobbin case that is catching the thread, or your bobbin is loosely/badly wound. You need to rule out the possibilities step by step until you find the cause. First, review your threading procedures from start to finish, using your user's manual. Then, without fabric, turn the hand wheel by hand (ALWAYS towards you) to see if you can see it start to catch. The top thread should rotate smoothly in the bobbin area. You should be able to pin-point the cause that way.

guide the the thread through the tension assembly and test
it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or
something in the middle. Raise the presser foot and pull the thread through the
tension. It should pull easily!! Lower the presser foot and pull the thread. It
should pull noticeably harder.)If it doesn't work like this, then there is probably thread stuck inside the tension assembly. Set the tension to zero and blow hard between the discs to dislodge the thread. If it passes this test, continue up through the
take up lever,then down through the thread guides to the needle.
Check to be sure you have the correct bobbin and that it is inserted the correct way.
OR remove the needle plate to remove the bobbin case. Look for any burrs or rough spots. Use a fine emery stick and steel wool to remove and buff them Reassemble and try again.

Take the thread completly off the machine and rethread it making sure it goes thru the tension wheel properly.
FYI Loops on the bottom-- Problem is in the threadding.. Loops on the top, problem is with the bobbin.
SOURCE: get everything threaded and when I go to sew it
Hello,
Here's some solutions to try.
* Re-thread your machine
It may be threaded incorrectly.
* Raise your feed dogs
If your machine has this feature.
* When you start to sew a seam, hold the upper and bobbin thread tails. Hold them back and out of the way as you sew your first couple of stitches. This will keep them from getting
caught in your machine.
I hope this helps you.
