Decals can be ironed on to ALL fabrics!IRON ON DECALS ONLY, SHOES NOT INCLUDED!!Step 1: Clean the area you choose to iron on! Make sure it's rid of all debris and let dryStep 2: Set your iron (I strongly suggest the use of a MINI IRON for best results) to medium/high heatStep 3: Place the decals with the CLEAR PLASTIC SIDE FACING UP onto the area you wish to apply them Use the tip on the iron to apply heat and pressure to the decal for 20-30 seconds Do NOT remove the plastic immediately afterStep 4: Before peeling, apply pressure with hands to make sure every part of the decal has fully adhered Once it has adhered, peel the heat resistant plastic cover off If there are any air bubbles or creases, you can put a piece of parchment paper on the butterflies and lightly go over it again with the ironStep 5 (OPTIONAL) If done properly the decal will have adhered permanently, however here are some extra tips! If applying to a shoe, I suggest avoiding putting the decals where the shoe creases, since they are subject to wear and tear, applying them on flat areas of the shoe will yield better results Furthermore, some customers use a top coats like acrylic sealant, mod podge, even nail polish gel to solidify the decals after application This step is not necessary, they will adhere without a top coat, but this can ensure your decals stay put!
