I did a framed shadow box type of thing a few months ago. My wife and mom
both scrapbook, and gave me some helpful suggestions and materials.
Your flies should mount fairly well with "mini glue dots". My mom got them
from a Stampin' Up! catalog. Worked good for me. For the tying
instructions, I would experiment with printing them on plain white paper
until you get the spacing and layout you want, then print them on your
color choice of card stock, mount the card stock to your tan cardboard
back with some of the acid free tape squares used for scrapbooking. As I
said, these ideas worked for me, they should work for you too.

Good luck,
Jeremy Moe

Just the type of information I was looking for, Thank you.
