I’ve only recently found out what it looks like on a tree, from a unique, Husband and Wife woodworking team. I’ll post their link at the end. They have a whole line of unique pieces, hand carved from Burl, they acquire themselves!
Burl can be found on many high end, obscure furniture pieces. It’s exquisiteness is like no other.
Photos shown here, are pieces I've refinished Some may still be available, check availability under Current Works
Visit my "lumbersexual carvologist" friends Chris and Lisa at Maderhausen Desgins, on Facebook.
Coursing the wild woodlands of Montana to bring you hand-carved decorative pieces, made from natural tree burls and anomalies. BTW...the ship EVERYWHERE !
