Minecraft blanket

So, today marks two weeks since I started on my son's Creeper blanket, and I thought I was doing pretty well. After all, I'd managed to go from this on the first day:

To this:

And finally to this:

It was originally supposed to be a 10 by 10 square creeper face to cover his bed, and so I intentionally made the squares about 7 inches across, so that it would cover his whole bed. The whole thing was going to be around about 165cm in each direction.

However....

My son has since decided that he wants the design changed, to accommodate his name as well... I have two choices. I can either scrap what I've done, (which is about 70 by 21 inches of blanket!), or work around what I've done and just add the name on once I've finished. I opted for the second option, and ran up a quick design on squared paper:

Unfortunately, the finished size of this design is about 231 x 297cm. My son only has a single bed, so this would drown it... Making the squares for his name a bit smaller I managed to shave off around half a meter in each direction, but the problem remains... His bed is 90 x 190cm... If I make the changes he wants, then he won't see them when it is spread on his bed.

He would know it was there I suppose... Maybe that is the point?
