Something I want to knit

I knew if I kept looking at yarn catalogs I would eventually find a kit I just have to make.  There is a pattern that screams up at me from the page and wont let me close the catalog.  I must have this.  I must make this.  It involves techniques I have never tried and a design I can’t get off my mind.  It is even on sale so the cost of the kit is less than the cost of the yarn purchased separately.  Do I buy this and make it mine?  Is there such a thing as to many hats?
