For years I have made my own. I use 1" red/orange flagging tape on white computer paper. Mostly I hold on the lower right hand corner with the cross hairs aligned along the bottom and right side. The bullet holes show up well on the white paper background and on the tape. Few of my guns are quarter inchers so any "floating" due to the colour of the tape is of little concern.
Within the next couple of weeks I have to have a cataract removed from my right (sighting) eye. I noticed that my group sizes have been increasing for the last few months and I attribute this to the cataract. It has also been affecting my reading. I hate the thought of having an operation on my eye but there isn't any alternative.
