Hi this is my no sew fish pattern completely designed by me, it was tested on my Instagram @summerdoescrochet

Materials
Hook
Yarn
Stitch markers
Safety eyes
Scissors
Stuffing (polyfill or yarn scraps ends work well)
Pre notes
Yarn and hook sizes
DK- 3mm
Aran- 3.5mm
Chunky-5mm
Plush-6.5mm
Jumbo-8mm

I always use a few hook sizes smaller the suggested with amigurumi as it makes the stitches tighter to prevent any stuffing from showing through. This pattern can be down with any weight yarn to achieve different sizes.
Use a stitch marker to mark to first(or last) stitch of each round to keep track - you can use a safety pin or a scrap piece of different coloured yarn if you don't have a stitch marker.
