An adjustable jig for securing a textile during assembly. The textile may be an upper of an article of footwear. The jig includes a plurality of plates displaceable in a first axis and/or second axis, each plate with one or more pin attachment sites. A template is placed on the jig and pins are placed into each plate to set the pin pattern. The template is removed and a textile is mounted to the jig using the pin pattern. The jig may be configured to accommodate different sizes and shapes of textiles, and is resistant to heating and mechanical forces.
