I know the pain all too well, hehe.
I made a blanket (crochet) for my bf last year and thinking about his height (6'4") and cozyness, I decided to make it......a bit oversized.
I sort of messed up the measurements and how many stitches I needed for it, so it ended up being a mammoth of a blanket.
I haven't really measured it: http://www.cafenox.net/graphos/main.php?g2_itemId=503 (he's standing in the loft of my previous apartment. It nearly touched the first floor).
By the time I was done with the seaming and weaving, I was sick of it. But I loved it to bits after I gave it to him, hehe.
The first thing he did was wrap himself in it "burrito" fashion. And a year later, it's the only "flat sheet" on his bed.
