Why, why, why?

I've bid, and won, on a sewing pattern on ebay.  It looks an amazing pattern.  You take seven yards of fabric and gather it into a neckline, as far as I can see.

I got the picture of the sew essentials website, which looks quite good.  The link is here.  I am saving the site and planning to go back there.

Why have I bid on a pattern that looks insanely tough for my very basic skills?  I haven't even got the dratted sewing machine out of the dratted box.  I cannot imagine ever having the courage to wear any of it, and I don't know anyone who would either.

And why am I mad enough to get a pattern that needs seven yards of material that is unlikely to come in at less than £4 per yard when not only will I be completely out of my depth but also unable to use the cheap sheet/duvet cover/pillowcase stash because it is such a particular fabric?  It will cost a fortune to get right.  Where am I going to draft out the pieces - after looking at those gathers the pieces will be enormous.

I know why I have had my mad moment.  Yes, I will love having a go at some point at the dracula nightie, but really it's because father has been refusing medicine and isn't eating enough.  There are worse things to displace with.
