Re: using canvas type cloth fabric to cover wood floor
Your plan of attack is probably the best one.
Other things you will need to consider is how to pull the fabric taut so that you don't load it up with wrinkles and folds. I would suggest doing some sample boards with different techniques and find one that will transfer to full scale with ease.
DO NOT use Minwax Poly, it is complete and utter junk!!!!!!!!!! You also want something that is rated for use on floors, which most poly's are not. Take a look at General (that is a brand name ) and McKlosskies finishes.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
