Bulu means ‘fur’ in Indonesian.

To achieve this furry look on the cat, first you need furry-type yarn like mohair or brushed wool/acrylic. However, plain wool/acrylic yarn can be made slightly furry too.
For this cat I used Red Heart Symphony (furry) and Lion Brand Vanna’s Choice (plain).

Second, you need a pet brush.
Pet brush can do wonder ;)
