*Amount of fabric required is dependent on your child’s size. This costume was made for my five year old son who has the following measurements:
Create the Fish Pattern
1. Print out your free fish costume pattern and assemble. If you prefer a different look for your fish, use the poster board to design your own fish pattern. You can make any shape you would like but I stuck to a more bubbly rounded fish.
2. If you’ve drawn your own fish pattern, cut it into separate parts so you have the following: head, body, tail and fin. These will be your pattern pieces for the fish. I added a tiny piece of poster board at the opening of the tail so it had a part to attach to the body later.
Cut Out Your Fabric
3. Fold your fabric so the right sides face out. Using your fabric pen, trace around the head and cut out. You should now have two fish head pieces in your head/fin fabric.
4. Cut out two more head pieces with your batting. Take your two satin head pieces and face them right sides together. Place a layer of batting on the top and bottom so your head pieces are layered in the following way:
5. Pin around the head, leaving the longest edge unpinned, and stitch together with a 1/2″ seam allowance. Be sure to leave the longest edge open because you will need it open to insert the foam.
6. Repeat so you have two stitched head pieces.
7. Next, it’s time to make the fin. Repeat steps 3-5: Trace the fin, cut the fabric, cut the batting.
8. Pin around the fin, excluding the large opening. This is the part you will attach to the fish. Be sure to leave room so you can turn it right side out. Sew around the pinned area.
9. Repeat so you have two fin pieces.
10. Repeat steps 3-4 with your tail pattern.
11. Pin and sew the tail pieces and batting, leaving an opening at the bottom of the tail so you can turn it right side out.
12. Next, fold your fabric in half and cut out two body pieces using the fish body fabric. This fabric is my favorite! Make sure you figure out which way you want your scales facing before you cut. Cut out two batting pieces as well using your fish body pattern.
13. Take all your pieces for one side of the fish (1 head, 1 body, 1 ) and lay them out so you know where you want the placement of the fin and face.
14. Pin the face of the fish to the body. Make sure to pin through both sides with the batting facing out. Stitch in place, making sure to only sew the front layer and front lining together and then repeat with the fish back and lining. This will ensure your fish is one piece.
15. Pin on the fin and sew the entire body making sure to leave an opening so you can insert the foam. Flip the body right side out.
Pro tip: Make sure to stitch around the fin, not across, to attach to the body. Stitching across will result in the fin getting stuck on the inside of your fish body!
16. Cut out a foam sheet so it’s the same size or slightly smaller than the fish. This does not need to look perfect, you just want it to fit nicely inside the fish.
17. Roll the foam and insert it into the opening. Once inserted, open up the foam and fit it into the fish.
18. Take your glue gun and glue the opening shut or hand stitch closed.
19. Repeat the above steps create the second fish body.
20. Cut out a tail fin from the foam and insert into the fin.
Pro tip: Cutting the foam in half makes it easier to insert into your fabric!
21. Now it’s time to attach the tail using your trusty glue gun. Glue the tail between the two openings in the back of the fish. Glue around the tail as well so that the whole back part of the fish is glued.
Make the Fish Eyes
22. Take your white and black felt and cut out four white eyes and two black pupils. Glue two white eyes together and then attach a black pupil in the center.
23. Glue the eyes onto the fish and glue the two heads together. Stop glueing before you reach the fish body fabric.
24. You should now you only have one opening – the middle of the fish. This is where your child will get in and out of their costume.
Attach the Straps
25. Measure the length of the straps by having your child put on the costume and see where the straps should lay so the costume fits comfortably. Cut the ribbon based on this length and pin into place.
26. Glue or hand stitch the straps into place.
Your fish is now finished and ready for some Halloween fun! Looks swimmingly!
