Based on the available information, there is no mention of knitting being a specific part of the 8th-grade curriculum in Slovenian primary schools (Osnovna šola). The curriculum includes compulsory subjects like Slovene, mathematics, foreign languages, history, physical education, geography, biology, chemistry, physics, music, and art education. While the arts are part of the curriculum, the searches did not reveal any specific details about knitting being taught within the art or crafts components of the 8th-grade curriculum. More specific information about the art curriculum for 8th grade would be needed to definitively confirm whether knitting is included.
