Ok this is totally random and crazy but I had to mention it. I wanted to get one of these months and months ago but they kept selling out.
These Quickdraw tape measures are so neat and a perfect stocking stuffer for the DIYer on your list!
The tape measure comes with a built in graphite marker to indicate your measurements without hunting down a pencil. Nifty eh?
The prices range from $14-24 depending on the size you prefer.
