A spouse takes on a lot of cost-effective roles, one of which is a nude model that doesn't require payment or leaving the house. Thanks to my husband, who is a super good sport. Foreshortening terrifies me, but I love the shoulder/armpit/upper arm area so much that I'm willing to work through it.
Once I get warmed up and feel comfortable with anatomy again, I like feeling the different thick-to-thins slide off the graphite oh so naturally. Made up people! Whee!
