Abstract: This disclosure addresses a problem in relation to the environmental destruction that excessive apparel production can produce. In various embodiments, existing textile products are deconstructed into pieces of fabric and then reassembled into apparel in a manner that creates minimal or zero waste. In some embodiments, the fabric pieces will be positioned inside of one or more pattern pieces so as to completely cover each one without overlapping its border. The positioned pieces will be treated with an adhesive and then have a paper layer adhered to it to hold the positioned fabric pieces in place while they are stitched together. Then, the resulting sandwich will be soaked to remove the paper and dissolve the adhesive. The resulting unified fabric component will then be available to be stitched together with other similarly formed fabric components to form a garment.
