hello Kees from the Netherlands!! i am so glad you posted your picture because i know you have been looking for those yellow ovals for some time. you may remember that i have some red and black ones. and maybe 1 or 2 of the yellow ones in my keeper cabinet but i have never seen a strand of them with any of the traders i visit. as Joy said, you should go to the Bead Trades section and post a listing on the Wanted page.
