I read recently of some on here whose dh made them a sewing extender for sewing larger objects. My dh and I looked at Lowe's today and are left wondering how do the dhs attach the legs for these to the main base under side. I understand putting feet on them but how does one attach those feet to the board? Anyone know and willing to share their plans and pics? Priced the plexiglass ones and had sticker shock. Lowe's carries 18x 24 pcs of acrylic which would work fine but what about those feet? Working on a king sized scrappy now and getting to big to deal with. Need an extender. Any help greatly appreciated.
