To attach under-the-counter appliances to a kitchen cabinet, we drill holes through the bottom shelf of that cabinet. Bolts run through those holes. For example, clock-radios, coffee makers, iPad holders, and over-the-range microwaves.
When later removing such items, we are left with unsightly holes left in that bottom shelf.
➥ Is there a way to plug or cover such holes?
I have heard of thin yet strong plastic patches with adhesive on one side that can applied like a Band-Aid, sticking to the remaining shelf while preventing anything from falling through or snagging the hole. But I have no idea what such a product might be called, or where to purchase.
