After nearly a year trying to find the size I needed in the colour I needed and at the price I wanted to pay - I was ready to give up.
Then a rather ingenious art teacher friend of mine, Carrie Hoyle, showed me a basic technique for making paper feathers. I've refined her technique a little to add some extra robustness and realism. This technique can be adapted to make a variety of feather types, but it allows you to make feathers up to about 20" or 40cms long for costumes and props.
They look reasonably convincing from anything over about 3ft or 1 meter away.
Step 1: Materials
In the UK and Europe you are looking for a paper or card with a weight of between 120 gsm and 160 gsm. I am not sure what this equates to in the U.S. or other countries.
You will need a ruler and a pencil or pen.
You will also need some thicker card to cut the templates from. Cereal carton card is ideal for this.
You will need some sharp scissors and (or) a sharp craft knife or scalpel.
You will need a pack of those thin bamboo kebab skewers (available at most large supermarkets).
A 'hot glue' gun and glue sticks. Possibly some paint or make up powders for colour.
Step 2: Making the templates
Using your scissors or scalpel, carefully cut out the template(s). You can now use these to draw around on your feather paper ensuring that you can get repeatable feather shapes for you project.
here are the first 5 templates I made to give you an idea.
