DO IT YOURSELF ENTRYPURPOSE: To enable individuals with upper extremity disabilities to fold any size paper up to legal size in half or in thirds. The device has a plywood base that clamps to the work surface. The far and right-hand edges of the base are bevelled and the top and left-hand edges have a stop. Two adjustable aluminum arms, based on the concept of the T square on a drafting board, can be moved along the front edge and screwed into the required position. To use, the user slides a sheet of paper from the table up the right-hand bevel onto the base, under the aluminum arms, and squared to the left-hand corner. To fold an A4-sized sheet in thirds, the first third is folded over the right-hand aluminum arm, the second third is folded over the left arm, and the folded sheet is removed by sliding. The journal article includes a photograph. SKILLS REQUIRED: Metal working, carpentry, and assembly. TITLE: In the Envelope. JOURNAL: TAD Journal. REF: Vol 22, no 1, Autumn 2002: p 17.
