Here are the instructions that I found on another thread and saved on my computer for future reference (my apologies to the poster of these instructions....(credit cannot be given as I did not save the poster's information)....I cannot vouch for these instructions as I have not tried to make a fish extender using them so I hope they work. We will probably be bringing our "original" fish extender along with many fish extender "locks" (zip ties)...so it doesn't go walking...or maybe I could try to talk Mom into making us a new fish extender!!!!!!
FISH EXTENDER INSTRUCTIONS
Make a rectangle pattern -- 9" x 30"
Make another rectangle pattern for pockets 9" x 6" - cut 4 sets (double - right sides together)
Put right sides together and cut one out double for front/back.
Cut a piece of felt that is 1" shorter than the pattern -- this will be your interfacing.
Cut out 4 pockets (doubled)
With right sides together, stitch top and bottom of each pocket. Turn and press flat.
Baste the felt to the wrong side of one of the pattern pieces.
Pin pockets to front of the fish extender that you just basted, matching edges.
Baste pockets along the sides.
Sew bottom of each pocket to the front of fish extender. I used a decorative stitch. You could also use some type of ribbon or bias tape.
Pin back of fish extender to front with right sides together.
Stitch using 3/8" seam allowance leaving about a 3 to 4 inch section unstitched to turn the fish extender right side out.
Trim corners and turn right side out.
Iron flat and stitch the unstitched section closed.
At the top of the fish extender, turn down to make a casing to put a wooden dowel rod.
Decorate your pockets . . . depending on how you're going to decorate your pockets . . . either decorate them before you baste them to the front of the fish extender or after the fish extender is totally sewn.
