Coffee jar paperweight

Well, I made the resin-filled paperweight inside my coffee jar lid, with a small paper rosebud set inside (not quilled - I made it using 10 heart shapes punched from red paper, a technique I learned ages ago).  It has turned out quite well, apart from quite a few air bubbles which have settled at the top of the layer of resin.  I'm not sure how this could have been avoided. Anyway, here it is for you to see.  And tomorrow I'm off to the supermarket to buy some more coffee!
