Dont bother with Officeworks,was in there last week & asked if they could print some apron bally art on self adhesive photo paper - they couldnt & they dont have A4 self adhesive paper -so to cut a long story short I purchased 100 sheets off ebay. The only thing is you can only use a inkjet printer (Not sure how the mylar will affect the ink).Let me know if you want me to print some tonight for you try - Havent printed anything yet,not sure how they will come out.
