Yes. Sorry, but this really does apply to all of us...

Unless your heart is truly set on the standard package offered by your undertaker (pine box, 20 mins at the crematorium, flowers and transport from home EXTRA) Leave Very Specific Instructions.
Go to this excellent site and make all your wishes clear.

And even if you have no clear wishes please let us know - so we will know for sure that we haven't short changed or mis-led you in any way at all.
