Is this ok? Shrinkie question..

Last night I was installing more Shrinkies in my own hair, as you know the difficult part is tryin to get the extension to stay in the shrinkie before you heat it (or maybe its jus me ;) ) so I thought id try something new,

I held the straighteners down on the very top of the tip for a few seconds until it kinda fanned out and found that it was so much easier to put them in this way as the tip didnt slip down the shrinkie, do you think this is ok??
