The big one ........... design walls!
Yes walls .... can never have enough of them!
If peg boards work for you, then go for it.
TBH I hate peg boards, whether in a home or a retail store.
The concept is great, but I have had so many of the hangers/hooks fall,
as I take something off them, that no way I would want them in my home.
Just my personal bug bear!!
Have fun designing the room of your dreams!
