You may use any desired yarn for knitting. To illustrate the detailed process of knitting in the photos, I used Kamtex mohair gold yarn (60% mohair, 20% cotton, 20% acrylic 50 gr/250 m).
The main color of the capybara in the pattern is beige, 1/10 skein.
Color of the swimsuit is pink baby cotton (100% cotton 100 gr/330 m) 1/15 skein.
D = 8 – 10 mm safety eyes or black beads
2 mm double-pointed needles (10 them).
Stuffing material, tapestry needle, pins, and row counter.
For knitting a swimsuit, a hook No. 2 and a button for its decoration are used.
