Why, thank you for the welcome and for the replies
I'm wondering if I might have to go with the larger clips (40 or 50mm) so that they stay in the hair and can hold enough. My 2 yo has a lot of hair! I guess I could try some of each. I do like that the 30mm can use the 3/8" ribbon since that seems more common to buy, at least here.
I'm going to go look at a ruler and see how big 30mm is. I'm can't visualize mm like I can inches
