Muri rusange, ubwoko bwamasahani buhendutse, kubera ko ibyapa byinshi bidafite ingese Nibyakozwe cyane, kandi igiciro ni gito. Igiciro cya casting kiratandukanye ukurikije ubunini bwimiterere. Kubabarirwa gutunganywa hashingiwe ku byuma bidafite ingese, bityo igiciro kiri hejuru yicy'icyuma gisanzwe kitagira umuyonga.

Ibyuma bitagira umuyonga Thimbles ikoreshwa muburyo bwo kubaka hasi kugirango irinde imiyoboro cyangwa impeta zicyuma zorohereza kwishyiriraho imiyoboro.

Itondekanya ryikariso: Ikariso itajegajega, icyuma cyoroshye kitagira amazi, icyuma cyuma, nicyuma.
