We use top quality stretcher bars are made of solid fir and Canadian basswood. This is a drier wood than pine and is less susceptible to warping over time. We staple all giclées on the back of the piece instead of the sides. We offer your choice of standard size bars that measure 11/16" deep and gallery bars that measure 1 1/2" deep. Gallery Street can even paint the edges of your giclee for a finshed look. Please see our price list for current pricing.
