A most desirable residence for the fairy folk.

For each little house, I used:
3 different coloured DK weight yarns for the stem, the gills and the cup.
A small amount of white DK for embroidery of the spots.
Snippets of felt in black for the windows and a bright colour for the door.
Embroidery thread.
Soft toy stuffing.
3 mm crochet hook

Why not add a loop and hang it from your Christmas tree.
