As you mostly know I've been crocheting some toys lately, and so that the toys appealed to the new baby in the family as well as the older children I added noise makers to most of them. Most of the fish have crinkly paper, bought on Amazon especially for the purpose, I shied away from using paper I had found that was crinkly due to worries it wouldn't be safe. I found that putting the paper around the inside of the crocheting and the stuffing inside that worked best. I used about 3 layers of paper and cut it to shape to fit the sides of the fish, slipped it inside then added the stuffing.
Rattles are easy, just throw them into the toy wherever, remember you can use more than one for more sound, this is especially useful if you have to use the smaller size rattle for smaller toys. The slightly bigger rattle creates enough sound I only used one.
I also had a noise maker that makes a tweeting noise as you shake it, like the rattles you can put them in anywhere, the trick here is to make sure that the toy is sewn together well because you don't want the head flopping around when it's shaken.
I had some pull cord ones, they came with very short cords, I extended them by crocheting them with extra yarn, make sure that all that pulling won't make your work come undone, use a strong yarn. An alternative here is to simply tie the short cord securely to the yarn and then start crocheting a longer cord and cover the knot with a breakaway bead, they are like a clam shell and snap shut around the knot. I continued to crochet onto a ring at the bottom, I have both wooden and silicon rings. The pull cords look better on either something like a doll where you can have the cord at the back or like I used it on a jelly fish and an octopus where the cord was lost amongst tentacles. Some of the pull cord noise makers have a hole for threading a cord through so you can tie the box that the sound is in securely inside the toy, otherwise each time you pull the cord you are pulling that box against the bottom of the toy.

Bells were my biggest problem. I loved the jingly sound they make but once inside the toy with all the stuffing the sound was muffled. Then at Easter I realised there were packs of hollow plastic eggs you could buy to fill with surprises for an Easter egg hunt. I bought a couple of packs in two different sizes and tried the bells inside them. It was much better but you couldn't still hear a clunking noise as the bell hit the inside of the plastic sides of the egg. So I crocheted little nests for inside the egg, this muffled the clunking sound to a more acceptable level, not quite the clarity of jingling bells outside a toy but the best I could come up with.

I hope this helps anyone else who plans on adding noise makers to toys they make whether sewn or knitted or crocheted.
Your toys are so neatly made very professional. X
Great tips sarah I found your tip for crinkle paper useful as I stuffed mine through out the stuffing with poor noise results , you really do learn on this forum thank you
Beautiful toys and very interesting. This would make a really informative and useful blog post. x
We can’t get Kinder eggs here they actually are one of the most seized at customs items. We get the Kinder joy egg instead that is really nothing like and doesn’t have the plastic egg.
The hollow eggs idea is great!
There are also hollow ovals inside Kinder Surptise eggs that would do a similar job.
Smashing selection of makes there, Sarah!
