Tips on Perfecting your Cosplay Helmet
1# To avoid wasting money, you can practice making your pattern first on paper. Cut out each part and tape them together to form a paper helmet. Wear it to check if it fits your head nicely and ensure that it reflects the design that you have in mind.
2# When creating your pattern, you can use a pen to mark the areas where you need to align your foam pieces to form a curve. You can use your thumb to line them up and create flushed seams.
3# Since a helmet has a curved surface, you should make sure that your contact glue or contact cement has the right consistency before gluing together your foam pieces. This is to make sure your pieces stay glued together and will form a nice curve and not get undone.
4# Use your heat gun after gluing all your foam pieces together to make the seam edges more malleable. You can then smooth out the surface if needed.
