Good grief...I hate seeing a good thread turn to crap, so I'll just pretend like I didn't see some of the previous posts. 
JJ:
I just sent you a PM.
This thread has me re-thinking how bad of a job I've been doing (but thought it was right!).
Sam: you guys really know how to knock this novice back a few steps and get us to the right track. THANK YOU!

So how do you guys give an accurate quote to the client before seeing the canvas/ metal in person?
First time poster, and new guy to the forum,and I have a question. In the past I have had to make several and I mean a pile of sanding blocks of varying configurations to suite my needs. But the problem is attaching sand paper to a piece of metal or wood and be able to replace it quickly.
I have tried to use various contact cement's which takes longer to apply than it takes to wear out the paper. Then most of the time you cant get the old paper off of the block without leaving bits and pieces of paper stuck to your sanding block.
If anyone could recommend an adhesive that works, fairly well I would be surely interested.
thanks D
