Puzzle Fun - Part One

I've been playing with these puzzle pieces I found in a bag at a thrift store. I do not know whether they are from a game, or what? But I had fun just putting together as many different things as I could come up with.

A butterfly:
A potted plant:

Christmas tree:

A flower:

Part Two coming up tomorrow, so please stay tuned!
