Rich and Mary Carty are the proprietors of Pinelands Folk Music & Basketry Center in Burlington County, NJ

With over 20 years experience playing and teaching hammered dulcimer, Rich Carty is known as “The Dulcimer Guy.” A multi-talented musician who is comfortable playing in a variety of styles, Rich has a large repertoire from which to draw.

Rich’s instrument — the hammered dulcimer — is an unforgettable solo instrument, but blends equally well as half of a duo, or as a special voice within a group.

Mary Carty is a life long resident of Burlington County, New Jersey, and brings her Native American heritage into play with her handmade baskets.

Many of her traditional baskets are shapes and styles with which her Lenape ancestors would have been familiar.

She is a true artist and innovator who does not like to have her creativity stifled by following rigid set patterns. This is a concept Mary often stresses to her students. “I don’t just teach people how to make baskets; I teach them how to be basket makers,” she often says.

On the other hand Mary has a healthy respect for tradition. This is why she has researched and makes traditional baskets which her Lenape ancestors would have made. It is this blending of tradition and creativity that makes Mary Carty’s baskets both unique and highly collectible. A talented basket weaver, Mary has won many awards for her original basket designs through the years, and has admirers throughout the world.

E. Lowell Jacobs:

E. Lowell Jacobs

Delaware’s ‘sea-level mountaineer’ and our banjo craftsman E. Lowell Jacobs started carving (whittling) his own toys from soft pine produce (‘orange’) crate wood shortly after getting his first pocket knife pre-teen. The boyhood home most remembered among a succession of several was a 20’ x 24’ four room house with a wood stove to heat it and no electricity or running water or plumbing, on two acres of mom’s families old homestead farm immediately adjacent to the Shawnee National Forest in Southern Illinois, roughly east of St Louis Mo and north of Paducah KY. Sputnik in 1957 made Lowell into a civil engineer and he has subsequently worked as such in California, Illinois and Delaware for the last 34 years, but he never really stopped whittling. He has done utilitarian furniture for his family and others, gunstocks, woodcarvings, large scale Church carvings including a full size crucifix, and countless small carvings very similar to those of 50 years ago. When he moved to Delaware and became interested in the five string banjo, and didn’t feel comfortable with the cost of one compared with the needs of his family, he discovered the section on Mountain Style banjos in Book 3 of the Foxfire series which looked like a doable woodworking project, so he built one, then another, and another, and then other styles including 8” piccolos and 11” dowel stick open backs, and a couple of bluegrassers, and one Strad pattern fiddle which doesn’t look very polished but sounds fairly decent, for about 175 instruments total, plus occasional repair work. He wrote several articles about banjo construction for Banjo Newsletter Magazine, and his work was featured on the cover three times. The 8” piccolos were particularly challenging as no parts were commercially available, so he had to build 8” block maple rims, an 8” tone ring, an 8” tension hoop, of course a short scale neck, and for resonator backed instruments, a downsized resonator and one piece flange. He is not amused by people that claim to have reinvented the block maple rim or who claim to be builders and the parts are identifiable as commercial components, and those who say they’ve built say “8” instruments and claim they’re a ‘builder’. Jacobs has more than 175 instruments to his little home basement shop credit and to this day says he doesn’t know exactly how any particular instrument is going to sound until it’s completed and maybe seasoned a bit. There is entirely too much self promotion and mysticism for ego stroking and marketing purposes around. The standard designs that have evolved thru the years are the ones that are going to work well for nearly all of us. Very few of these periodic ‘improvements’ are going to last. It would be a stretch to say Jacobs could probably build a banjo from a tree and a rock, but he’s been closer than most!

Guy and Karen Stinson

Guy and Karen Stinson come to us from the beautiful shores of Lake Michigan.  They’ve made Glenn their home for the past 47 years.  They are a husband and wife guitar, banjo duo.  In the local area they are fondly called The Glennbillies.

Guy comes from a long line of family musicians.  Many of his childhood memories are of night long jam sessions with country, folk and classic rock music aplenty.  He has been told by many that he is ‘a walking jukebox’.

Karen’s passion for music developed later in life.  She first picked up her banjo at the age of 50.  She hasn’t stopped adding to her repertoire of songs since she clawed her first string.

As a duo, Guy and Karen share their love of music by presenting volunteer performances at care facilities, schools, churches and community events; tunes for both young and old!  In 2017 they made their first journey to the Maryland Folk Retreat and found a wonderful family of fellow musicians to jam with.   They are looking forward to the 2018 retreat!
