Bulblets from either my orienpet or oriental lily

I'm so happy to have found that one of my lilys has multiplied like crazy. It was one big bulb - now it's 2 very big bulbs - 1 big, about 4 medium, 5 small and 5 Very small bulblets.

I planted all but the 10 smallest -- and i'm wondering if i can grow them on a sunny windowsill over the winter and then plant them out in the spring. I've never done this before, any ideas or suggestions would really be appreciated.
thanks

I just push them ever so gently into the soil but not to the point of covering them. Good luck with whatever you do and I'll be watching for answers along with you.
