Flush setting on Keum boo

Hello everyone!

I was wondering if it is possible to flush set into an area with
keum-boo. I am afriad the foil will buckle while burnishing the
setting. Has anyone attemped something like this? I haven’t seen any
keum boo work with a flush setting in it. I am a beginner to
keum-boo and will take any tips!

Thanks for you help! Peace love and metals,
C-
