Up for bid is a Perrygraf Fabric Care and Sewing Guide Slide Chart from 1989. Oh my goodness - so much information in a 4" x 9" (approximately) folder! Inside are "Cleaning Recommendation", "Characteristics", "Uses", and "Sewing Tips" for 14 different fabrics: from acetate to wool. You simply pull the tab on the bottom to move the red line to the fabric you're using to get the information. Viola! Super easy! It is in excellent used condition.
