Patchwork ironing occurs when a sewing or embroidery machine is applying heat and seal stitching patches within the 200-400°F range. DIY projects can be done using a steam home iron, but for commercial production, industrial grade heat presses are ideal for consistency. Along with type of fabric and adhesive, the type of adhesive also matters—in this case, silks perform best with low-melt adhesives. Culturally, the multifunctionality of tools impacts their design—compact travel irons geared towards small-scale crafting design in urban Asia, stubby irons serve North American hubs focused on bulk production.
