You can crochet this toy with your favorite yarn - cotton, acrylic, plush yarn and your favorite crochet hook. The height and width of your toy will depend on the thickness of the yarn and the hook size.
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 pictures in the pattern.

I recommend 100% cotton of any brand
The sample is crocheted with 100% cotton yarn (1.8oz) 50g Lace - red 100 yds , orange 100 yds, yellow 100 yds, green 100 yds , light blue 50 yds , blue 50 yds, purple colors 50 yds, pink -50yds, gray – 100 yds. Crochet Lace from a thread of 2 addition
Size: the height and width of 1 base cube is -2 inch/5 cm.
Hook-№ 1,2 mm- 2 mm . I used № 1.2mm hook . I know that many people find it very difficult to crochet with such a small size. This is why I recommend a 2mm hook.
