Margaret Carlson brings a whole new meaning to the term fabric art. Her astonishing construction, Husht Reverberations, is composed of over 10,000 yards of donated fabric, created with a lot of help from her friends. In its sheer mass alone, this is an impressive piece of work, and I'm told it's even more amazing in person. Carlson will exhibit this piece starting this week at Factory on 5th Art Space along with an undulating canvas work created by Christy Kay Lopez called The Observer Effect. The show opens Friday, March 25, with a reception from 7 to 11 p.m. Runs through April 25. For details, call 259-9029 or 255-3331.
