I dabble in card making as well and when I put ribbons on my card I use either scor tape or copic tape. It stays on there so well and just adheres to the ribbons I'm using. I'm going to try this with some alligator clips.
If you are looking for scor tape in Canada, I recommend Stamping Bella
. She is local to me and has Great shipping within Canada. I get my copic tape from the states where I buy my copic markers from.
