縫(feng)紉就是把衣片縫(feng)合(he)成服裝的工藝(yi)。可分為手縫(feng)工藝(yi)、機縫(feng)工藝(yi)、特(te)殊工藝(yi)等。

　　手縫工藝

　　采用(yong)(yong)手(shou)針進行(xing)縫制的工(gong)藝(yi)。是中(zhong)國的傳統手(shou)工(gong)技藝(yi)。很多針法(fa)及其作用(yong)(yong)尚不能用(yong)(yong)現代縫紉機替代。具有線跡精(jing)細、平整，針法(fa)豐富等(deng)特點，被譽為高檔工(gong)藝(yi)。　手(shou)縫工(gong)藝(yi)的主要工(gong)具是手(shou)縫針和頂針箍。絲綢等(deng)纖維(wei)較(jiao)細的織(zhi)物宜用(yong)(yong)7～9號(hao)針;鎖(suo)眼釘(ding)紐(niu)宜用(yong)(yong)4～5號(hao)針，一般(ban)毛料(liao)則用(yong)(yong)粗(cu)細適中(zhong)的6～8號(hao)針。
