txheej txheem dyeing
Txoj haujlwm yuav tsum pib ntawm cov ces kaum. Txhawm rau ua kom cov txheej txheem yooj yim, ib qho txhuam tuaj yeem siv tau. Qhov kev xaiv zoo tshaj plaws yuav yog siv cov xim hauv ib qho kev taw qhia, qhov no yuav xyuas kom meej tias tsis muaj qhov sib txawv ntawm qhov sib txawv ntawm lub qab nthab. Nyob rau hauv cov ntaub ntawv no, tib yam kev taw qhia ntawm kev txav yuav tsum tau soj ntsuam. Cov txheej tom ntej yog siv nrog kev pab los ntawm strokes, thim rov qab nyob rau hauv kev sib raug zoo rau thawj. Tom qab ntawd, txheej txheej yog smoothed los tiv thaiv streaks.
