Two pictures of my Vikings to date. I have the Christmas Viking coming, so I guess I'll have to rearrange everyone again. Maybe a new Detolf just for Vikings!
These figures are roughly 8 inches tall and about 5 inches wide with arms outstretched. You can fit 6 on a Detolf shelf, but if you place 3 elevated in back & 2 in front, (like the top picture) it makes for a better presentation. I have been experimenting with styrofoam, it works great for making tiers, can be painted (with latex paint only) or covered with cloth or wrapping paper, (which I have yet to do).
