Max..... They are my first 15mm but ive sculpted other stuff, 28mm...so ive had practice . I got a few different creatures im doing at the moment, ive been sculpting on and off for years but gave up dozens of times cos of frustration . if you use a needle , do you use a sharp one or a blunted/rounded off one? i found it you blunt the needle off at the tip it didnt tear or catch in the putty, thats just what i found anyways, youve got the hang of it all right!, aint chainmail all different in sizes though? some is tightly knit together and other less so? in real life i mean. not and expert , just stuff ive seen on the net etc, etc ......
