My apartment building has a mangle in the drying room. I have been using it, but folding my bed linens has proven difficult. In particular, getting the duvet covers' seams to remain as the edge of the fold is challenging. Keeping the sheet flat when it goes in the mangle is also difficult, resulting in a few creases in the end that goes in last.

My current system is to hold the linen off the floor with my hands up and trying to fold it. This usually involves standing on my toes for the sheets. I fold duvet covers in three, and sheets in four, moving the top leaf around for a "Σ" shape. I'll usually end up dragging the sheet along the floor when feeding it into the mangle.
These are the results I get:
Are there any tricks to keeping the folds straight, and keeping the sheet off the floor while feeding it in?
