LOL, when I was give a gift cert for $100...lol...I got sock yarn..yep...all sock yarn
But, it's all in what you like...they have LOADS of yummy accessories and very good books as well as the yarn...it's a hard call...if I had another $100 I would probably go accessory/book crazy

Your hubby is a VERY GOOD knitter's husband...like mine...u r very lucky...

Mine is constantly buying knitting things for me or doing just as your has said...give him a big pat on the back from me
