I do not use any clips, I'm a 'scruncher.'
I have found one thing that really helps is some sort of quilt support left of me. Something permanent there is just not practical in my situation, but when I need it, I have a board, seems about 1/8" thick and the dimensions of the open top drawer.
I think anything is that area to support the quilt would help.
(I have been married and lived here over 32 years and just recently got this setup. Lesson learned - good things come to those who wait. And wait. And wait.)
