Nal Sudhan ah Kalky Ragged waa nal sudhan ah oo leh muraayad (shade) laga sameeyay warqad daabac ah (tracing paper). Muraayadda waxaa lagu soo saaray tignoolajiyad gaar ah oo la horumariyay, taas oo isku darsan midab-gelin gacanta lagu sameeyo, dhuuqid (impregnation), tolid, iyo dabaqad (riveting). Qaab-dhismeedka daloolka leh ee muraayadda ayaa aad u dabacsan, taas oo suurtagelinaysa in muraayadda la rogo si loo helo qaab nal ah oo gebi ahaanba ka duwan. Rogitaanku wuxuu u baahan yahay oo keliya in la beddelo meesha lagu rakibay hayaha isha iftiinka, waxaana qaadanaya ilaa toban ilbiriqsi. Cidhifyada gacanta lagu jeexay ee qaybaha muraayadda ayaa si cad ugu kala duwan cidhifyada si toos ah loo gooyay. Nalku wuxuu cabbiraa 60 santimeetir bogga, 60 santimeetir dhererka, iyo 30 santimeetir gudaha, marka aan la tirin xadhiggiisa.
