The lining arrived and I finally got it cut and attached. I used the drawer cutout to get the general shape for the sides and then fine tuned from there.
Also put some in the base to help center the drawer better (used a piece I miscut). Was easy to apply and could reposition and it seems to be stuck in place (used this product). Would like to try flocking at some point, but thus was pretty easy and definitely adds a nice touch.
