How many of us have drawers in our kitchen that look like this? I have quite a few. I am also not a fan of the ones that you buy in the store because they just slide around, and they never stay where you put them.
So out of some simple trim pieces that I bought from a hardware store I made my own, and they will never move.
1st - I cut my trim pieces to make a rectangle that are the exact dimension of my drawer.
Next - I glued them together and slid them in place, you want a nice snug fit so that they will not slide or you can also glue them in place.
Now I have a few more drawers to do.
