Cradle problems!!! help!!!

So I bought a gorgeous heirloom cradle - a Bellini oval shaped cradle to be exact and because I NEEED the oval cradle now I'm stuck not having sheets for it!!! The stokke sheets are too long for this cradle and regular bassinet sheets are too short. Does anyone have a similar type cradle? If so, where did you get your sheets!!! I'm doing a test run in my garage befor washing everything and these are just too big!
