Please note all items are made to order by Pink Bird Originals & production time can take between 3 - 5 days. Size: 7cm x 10cm How to apply patch to fabric: Patches are waterproof to an extent. Do not tumble dry. For washing machine use, use a cool wash. Would recommend hand-washing if possible. Washing at a high temperature will affect/damage the adhesive backing. Patches come with iron-on adhesive backing Heat-N-Bond Set the iron to the cotton setting or equivalent Peel off paper liner Place the patch adhesive side down on top of your fabric then iron from fabric side onto patch. Press & hold the iron on the patch for 10-12 seconds until the entire piece has bonded. For thicker fabrics, a longer time may be required. DO NOT PRESS IRON DIRECTLY ONTO LEATHER EFFECT OR HOLOGRAPHIC MATERIAL: this will destroy the patch, only iron from reverse side of patch. Remove iron & press patch to fabric ensuring the patch & the material are flat. It is imperative that you wait for your patch to cool completely before testing to see if it’s secure as bonding only takes place when the adhesive has completely cooled. Heat-N-Bond also recommend you either hand or machine sew along edges of the item to the fabric for extra security. Embroidered Human Heart Organ Iron On Embroidery Patch
