hmmm... a fun t=shirt, a pair of nice jeans, leather belt for going out in that jeans, "I hope they serve beer in hell" book lol.... a model kitset (to assemble and paint) of a hotrod, preferabally, a '1932 Roadster with a Hemi, or a 1957 Chevy fishtail, or a T-Bucket hotrod, its be few hours of careful doing, and its a great art peice to put on shelf and look...
if your hubby or boy likes to use video camera, maybe a fisheye lens to attach on camera (but you'd need to show video (or stills) to the camera shop for assistance to pick, Raynox is a good brand)...it makes filming and photography more fun...
if hubby like to play electric guitar, get a USB audio interface (either Tascan or Scarlett, point is has to be USB 2.0 dont waste time with a USB1.1 or usb 1)...plug in guitar, mike and record make music into computer...fun (i have both for film making)
a nice tie for your hubby? ,
a good baseball cap for your boy?
hope my ideas helps
Happy Christmas Frisky
