Hi, Frank,
In my area, the scroll saw portraits are not nearly as sellable as Intarsia or Out-door lawn ornaments, and things like that.
Fortunately, the portraits can be stack cut so, if I am cutting anything like the tiger you described
I cut at least 3 of them which technically makes the cutting time 3 times less than one at a time
and you can sell cheaper because you don't have as much time involved.
If you use a formula like Ray (EIEIO) mentioned about
Cost of material, plus the hours it took to cut times how much you want to make per hour
you can get an estimate of your desired price because you have set an amount for how much you want to make per hour.
Good luck and God Bless! Spirithorse
