Does everyone use velcro to secure their cameras, and if not, what would you consider the best method? Is it really essential to have a "pocket" for the button to sit in, or is there a better way? I have tried several adjustments but something about the way I move seems to always cause a scratching noise during video shops when walking. It's so annoying, and I am trying to be the best I can. Also, as I improve I am looking for more shirts but black button style shirts and/or dresses seem to be hard to find. Any particular brands that offer prints that are more camera friendly?
