Joe, the best gloves I've tried are called Machingers. Here is a link:

There are other gloves that have nubby bumps on them. I always use gloves to machine quilt, and most of the machine quilters I know also do that.
It sounds to me like your feed dogs are dull, dirty, or used up and need to be switched out. It's a fairly simple thing to do. However, many machines have trouble with bumps. In that case, you need a hump jumper. Here's a link:

So for less than $20, you can end your problems!
Now let me ask you a question: My 127 was dead for 40 years when I brought it back from the dead. I still have trouble making a good stitch, tension wise. The stitch is loose. I'd rather get a new head than change the tensioneer, but maybe... Do you have any suggestions?
