This fly box is easy to make and very handy. You can make it with an Altoids tin or lacking that, I used a Sucrets tin.
Step 1: You Will Need:
A glue gun, window framing insulation, (or any thin closed cell foam) a altoid tin, and a piece of cork. (optional)
Step 2: Trace
Trace the shape of the tin three times on the foam. Make sure not to trace the lid.
Step 3: Cut
Cut out what you just traced.
Step 4: Corked
Cut a small piece of cork so the lid can still close and glue it on. (optional)
Step 5: Glue
Glue in each sheet of foam, one on top of the other.
Step 6: Glue Some More
I would suggest gluing around the edges of the final sheet to seal it up.
Step 7: Finished!
Fill the box with all your favourite flies. The cork strip is to dry your fly after use. All flies pictured are tied by me.
