I just finished watching the new “Begin here step by step” videos and I see you haven’t mentioned using a spray fixative.
Do you use one for your finished drawings?
Could you please recommend a good fixative spray that would work for graphite and maybe Prismacolor (if they need it)?
BTW, are Prismacolor pencils archival? Since you used them for such a long time I guess you know best how the drawings behave.
