can you tell what it is?

This is a kind of halfway house of a post. I am partway through making something and although the crochet part is finished there is still another day (hopefully thats all) to be done on it.

I have been through my stash and decided I have quite a large one (oo-eer) and that really I cant justify buying anymore until I use up at least some.
I very rarely use aran wool but I bought quite a bit-6 balls for a throw-that I have never completed and that I'm not overly enamoured with. So I decided maybe it would be good to use all that up and then I know I have only two (more special) balls of aran in all of my stash. 
I decided to give a ripple a go-I have done it before-twice-once with a cowl/scarf which again, is ok, but not something I cant live without-I know I'm abit flighty with my makes. The only time I tried it I made a baby blanket- a rainbow one and I loved it, the end product...making it was a nightmare. However, after making this itam I cant see why, this was a drem and as I was using aran yarn I was able to use a 5mm so it grew at a reasonable rate.
So here we have it...on my knee as I hook away. 

And here it is laid out on the table...it runs almost exactly from one end to the other conveniently, any guesses? thats it pretty much in its entirity-Since the photos I have added a thin border-of doubles down each side and there is some slip stitches needed...any ideas?

I'm hoping to finish it tonight or tomorrow morning and I will post a picture of the finished item-unless Ive made a pigs ear or it, then I'll deny this ever happened!
