Nsalu zoluka ndi chinthu chopangidwa 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 mu nkhosi ziŵiri zotchedwa “malekezero othawirako”. Zotsirizirazi zimadyetsedwa muzitsulo zachitsulo pazitsulo, kumene zimapanga ukonde wolumikizana wotchedwa "fill" kapena "ground knit," womwe umapanga maziko a nsalu yoluka. Chigawochi chikatha, zigawo zowonjezera zokhala ndi mitundu yosiyanasiyana zikhoza kuwonjezeredwa mpaka mapangidwe omwe akufunidwa akwaniritsidwa. Potsirizira pake, zigawozo amazilumikiza pamodzi m’malo osiyanasiyana m’litali mwake ndi nsonga zotchedwa selvedges, ndiyeno amadulana wina ndi mzake kuti apange chinthu chomalizidwa, chokonzekera kukonzedwanso, monga kudhaya 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 nsalu zoluka, chifukwa palibe chifukwa choluka movutikira ngati choluka kapena chotchinga - m'malo mwake, zowongola zimangolumikizana, kupanga midadada yolimba kwambiri, m'malo mokhala ndi mawonekedwe a chikhalidwe chitsanzo. Nsalu yozunguliridwa ndi kalembedwe kovuta kambiri kakang'ono.
