My Dad drew the heart and lungs with the outline of a deer on a piece of cardboard and stuck it on a hay bale. Zero cost and it got the point across. Being a youngster, she might not like the sport as much as she says she will. If she still has the fire after a couple months of shooting at cardboard, asks questions, and talks about hunting, then I might consider dropping the coin on a good 3D target for her. My daughter was all into archery for about a year. She wanted her own hunting bow and the whole nine yards. I bought her a good inexpensive non-hunting practice bow and she shot it for about 2 months during the summer in preparation for the season, but then didn't even wanted to sit with me in the stand during bow season. I even went hunting bow shopping with her to try to rekindle the interest, but no dice. After that first flare up, she decided she didn't like bow hunting and never touched it again. Go figure. I gave the practice bow away to a youngster last summer and he's just about wore the thing out. Good luck and I hope she keeps the interest better than my daughter.
