Never heard of lace maple. Has it another name?
I believe the “lace” refers to the style of grain configuration, also referred to as “Veil Maple”. It’s one of many grain anomalies found in maples, ie. birdseye, lace, veil, quilted, Burl, etc. It can be enhanced by the way the log is cut, 1/4 sawn, etc. its also common in yellow birch, although not as pronounced.
