Step 12: baked

this is what it looks like baked.. that gap goes away once you twist the top..

also dont use sculpey to make bowls... bad bad idea... 

One more thing.. i drilled a 3/hole on the metal cap.. and on the sculpey top.. and plugged my 3/8 hose in it.. i found that making the hole while the sculpey is hard a lot easier than when it's fresh.. because like i said plastic doesn't like ovens and hoses are made of plastic
Wonderful job on this, Looks great and as a cookie jar would be a great gift for any star wars fan!
