Oh no, not again!

After the rigours of two difficult puzzles, I chose an easy one at the weekend. It only took me one evening (Friday), I left it out to admire on Saturday, then broke it up and packed it away on Sunday.Then, yesterday (Monday) I found a piece on the floor! ( the third time this has happened within the past few months)
Again the quandary - was that the only piece I had dropped? These puzzles are made of wood - nice and small for little doggy mouths to pick up and chew  - both poodles love wood! 
No alternative but to do the puzzle again - I would be annoyed and embarrassed if I lent it to someone and there were pieces missing.
So here it is - finished  - and complete!!
I don't think I actually drop the pieces - I make the puzzles on a  deep wooden tray - they can't slip off and then they go into a cloth bag before putting in the box. I think, they must cling to my sleeves then drop when I stand up.
In future I will roll my sleeves up before breaking the puzzle!!
