Thanks to all who replied, I am going to buy a thin plastic type ruler from
a Lin-craft shop here in town. It's a material type place, I will cut off
the excess of what i need and cover it with a 6 inch wide piece of clear
contact adhesive so as the wood wont catch on the edge of the tape.

I also would like to swap kitchen cabinet ideas from any one who would like
to swap emails and give me ideas.

Thanks once again
