Nsalu zoluka ndi zinthu zopangidwa kuchokera ku miluko yolumikizana ya ulusi. Ikhoza kupangidwa ndi makina kapena njira zowomba pamanja ndipo nthawi zambiri amagwiritsidwa ntchito popanga zovala. Nsalu zoluka zimakhala ndi zinthu zapadera zomwe zimasiyana ndi nsalu zolukidwa, zomwe zimapangidwa ndi looms osati singano.

Njira yoluka greige imaphatikizapo kugwiritsa ntchito makina angapo apadera kuti apange mawonekedwe omwe amafunidwa komanso mawonekedwe pansalu. Choyamba, mpukutu waukulu wa ulusi umadyetsedwa mu chipangizo chamagetsi chotchedwa warper, chomwe chimakonzekeretsa ulusiwo kuti uluke pamodzi kukhala milusi iwiri yotchedwa "warp ends." Zotsirizirazi zimadyetsedwa muzitsulo zachitsulo pazitsulo, kumene zimapanga ukonde wolumikizana wotchedwa "kudzaza" kapena "nthaka yolumikizana," yomwe imapanga maziko a nsalu yoluka. Chigawochi chikatha, zigawo zowonjezera zokhala ndi mitundu yosiyanasiyana zikhoza kuwonjezeredwa mpaka mapangidwe omwe akufunidwa akwaniritsidwa. Potsirizira pake, zigawozo zimagwirizanitsidwa pamodzi m’malo osiyanasiyana m’utali wake ndi nsonga zotchedwa selvedges, kenaka amadulana wina ndi mzake kuti apange chinthu chotsirizidwa, chokonzekera kukonzedwanso, monga ngati kuchapa kapena kusindikiza ngati kuli kofunikira.

Kusiyana kwa nsalu zoluka ndi zolukidwa makamaka ndi momwe zimapangidwira. Nsalu zolukidwa zimakhala ndi magulu a ulusi wowongoka womwe umalumikizidwa, pomwe nsalu zoluka zimakhala ndi malupu omwe amalumikizana molunjika mbali ina (yotchedwa "sokisiti stitches"). Izi zikutanthauza kuti nthawi zambiri pamakhala tsatanetsatane wocheperako poyerekeza ndi mitundu yoluka, popeza palibe chifukwa choluka movutikira ngati choluka kapena chotchingira - m'malo mwake, zowongola zimangolumikizana, kupanga midadada yolimba kwambiri, m'malo mokhala ndi mawonekedwe a chikhalidwe chitsanzo. Nsalu yozunguliridwa ndi kachitidwe kovuta kambiri kakang'ono.
