[ adjective ] done by hand without mechanical aids or devices
"a freehand drawing"
Used in print(Chester G. Starr, The Origins of Greek Civili...)
The potters , in_particular , had virtually eschewed freehand drawing , elaborate motifs , and the curving lines of nature , while yet expressing a belief that there was order in the universe .
Painters left less and less of a vase in a plain dark color ; instead they divided the surface into many bands or covered it by all-over patterns into which freehand drawing began to creep .
