That's a common problem, NickiZ. Some people use a stiletto to help manage the fabric. Other people use enders more than leaders to butt up against that last bit going under the foot. Sometimes what foot you use can make a big difference, I'm so used to 1/4" quilter foots I have problems using anything else. Some machines require guiding the fabric and then we need to learn how to not guide the fabric and let another machine take care of it.
My "good" machine needs a servicing so I have my cheapo Brother out, and I'm having a hard time getting used to it again. I have not been impressed with workmanship but the bad stuff is hidden in the back and I'm getting better each seam I do.
The walking foot helps more (I think) with going from areas of two thicknesses of fabric to the bunches of seams as well as shifting layers (sort of the same issue). The Bernina has an integrated one and for the most part I leave it on.
