Chilema ndi Kusamalira
Chilema
Zolakwika zapamtunda zomwe zimadutsa kupitirira 12% ya makulidwe a khoma kapena kupitirira pang'ono makulidwe a khoma zidzatengedwa ngati zolakwika,
ndipo zofooka zowoneka zowoneka kuti ndizozama kuposa 5% kuposa makulidwe a khoma lomwe nthawi zambiri limatchedwa nkhanambo, seams, laps, misonzi, kapena magawo.
Kusamalira Chilema
Zowonongeka zitha kuthetsedwa pogaya, malinga ngati makulidwe otsala a khoma ali mkati mwa malire odziwika ndipo malo opindika osalala amasungidwa.
Zigawo za chitoliro zomwe zili ndi zolakwika zikhoza kudulidwa mkati mwa malire a kutalika kwake.
