Basically Micaela asked anyone who wanted to be involved to drop her a line and let her know. From that point she arranged it (and I've no idea how, I would have been so confused as so many people were involved!) like a Secret Santa so that no two people had the same to swap.
The person I had the pleasure of sending something to was Lisa from Three Ladybugs Love to Play. I picked to send her these two ornaments which I loved and wanted for myself!
The person who had me as their swap was Chels from The Well Nice Chronicles. The lovely girl had sent me this great ornament:
It looks so cool on my little pink tree and I'm so grateful!
A big thank you to Micaela for hosting and organising, and to Lisa and Chels, whose blogs I am glad to have discovered!
