The radius on the corners is 1/2". I use a single piece of 10 mil, paper backed veneer to wrap around the sides and front. Also, I usually cut the piece of veneer approximately 1/2" oversize so that it can be lined up on the cabinet and then trimmed later. I like to use a heat sensitive glue by the brand name of Heat Lock. You can use other adhesives, but I like using the heat senstitive type. Simply roll on the glue with a foam type roller or brush on to the back side of the veneer and on the surface of the cabinet. Normally like to use two(2) coats on both surfaces. When it dries, simply iron it on with a clothes iron set at medium heat (midrange on the temperature setting). Best to use a piece of cotton cloth ( like an old tee shirt) between the iron and the veneer to prevent scorching the veneer. Line up the veneer and start at one end and work your way down. Trim the veneer with a laminate or veneer trimmer or a utility knife so that it is flush with the endge of the cabinet.
I normally like to veneer the the sides and front first and then the top, bottom,and back in that order. When finished, lightly sand the veneered cabinet with 320 or 400 grit sandpaper, then wipe throughly with a tack cloth to remove the dust. Prior to applying a stain or just a polyurethane finish I suggest using Minwax brand or similar Prestain for a more uniform wood tone finish.
Hope this suggestion was helpful to you.
