Hello Roy,
Being quite new to this sport, I can only offer what has worked for me so far! I'm sure the others can come up with some other solutions that work better but this is what I do sometimes. Print it out on regular paper, then spray the back with a bit of paint! It seems to hold the paper together more!
As for the target, I can give you the sizes of the circles if you want to draw one up! Remember, there are 15 of them!
