Felt, with its broad range of colours, no-sew ease and ready availability, is one of the most frequently called for items in craft projects. When you need felt with extra substance, for a free-standing project, for instance, try coating it with a special liquid to make it stiff. Find fabric stiffening products near the adhesives in craft and fabric stores. After you stiffen the felt, you can cut it, glue it or stitch it as usual, into whatever design you require.
Pour the liquid fabric stiffener into the bowl. Place the felt onto the plastic cutting board.
Dip the paintbrush into the fabric stiffener and apply it to the felt in a thin and even layer. Coat the entire side of the felt with the fabric stiffener.
Turn the felt over. Coat the opposite side of the felt with the paintbrush using the same technique.
Allow the felt to dry completely on the cutting board.
Use the stiffened felt for the crafting project after it dries.
Consider using a spray-on fabric stiffener instead of applying it with the paintbrush. Spray-on stiffener may be slightly less effective, but application is easier and less messy. You may need to apply two coats of spray-on fabric stiffener. Make your own fabric stiffener by diluting white glue with equal parts of water and brushing it onto the felt as described above.
