You can crochet this toy with your favorite yarn - cotton, acrylic, plush yarn and your favorite crochet. The height and width of your toy will depend on the thickness of the yarn and the hook.
But from yarn with cotton after active games-the look will be much better than from 100% acrylic. If you immediately use a good yarn -100% cotton or mixed 50% cotton -50% acrylic, then the look of your toy will delight you for a long time.
Toys should be crocheted very tightly. Then when filling with filler
1 they do not stretch much.
2 the filler is not visible through the holes
3 they have a beautiful look like in the picture of the patterns.
