Five days? I think an IOU is in order. Meanwhile, get some fat yarn and big needles, cast on for the size you want it to be and knit every row. Garter stitch (every row is knitted) makes a great blanket. When you get to the length you want, learn to bind off.
Cheating is an option. . . . Cheaters never win and winners never cheat, but smart knitters who want to retain an iota of sanity do, cheerfully. ~~Kory Stamper
