Next you need to lay out the location of the loops. We made a zig-zag line back and forth across the base at a 45 degree angle as shown in the photo on the right. Each loop will be fastened to the base with a pair of wood screws from behind. Mark hole locations for the loops so that the screws will not hit the large hole you created in each loop. Drill through clearance holes for the wood screws.

Clamp a loop in the proper location and using the clearance holes that you just created as a guide, drill pilot holes in the bottoms of the loop to accept the wood screws. The clamp should be firm but do not overtighten because you might crack the loop. After drilling pilot holes, drive a pair of wood screws to securely fasten each loop to the base. Since we were using pine (a soft wood) we did not have to countersink the heads of the screw. Harder woods may require countersinking because it is critical that the screwheads be completely below the surface of the wood; failure to do this will make it impossible to seat the wine rack against the wall. To complete the assembly, drill three or four through clearance holes between loops to accommodate for the mounting screws. Make sure that you provide mounting holes at the ends of the rack and in the middle.
