Make sure to oil your airbrush up before putting it back together. Most artists find the using their airbrush without the needle cap gives them more control. Removing the needle cap is fine but should you hit your airbrush against something or drop it you could end up damaging the needle itself. So to take care of your airbrush make sure that when you are not using your airbrush that you replace the needle cap back onto it. You can heat set by placing a protect cloth between the design and the iron and ironing the design or you can turn the material inside out and place in the dryer on high heat. If the acrylic does not require heat setting on fabrics then you should still protect the design from fading when washed. To do this place the clothing into a sink of cold water and salt and allow to soak. If you want to use a more durable material to create your stencils you can use the plastic pocket folders. These can be picked up rather cheaply from the store in the office supply section or hit the back to school supplies. You will need an exacto knife to cut your design out. Depending on the size of your stencil you can probably create more than one stencil from this plastic folder.
