I bought wonder clips from Amazon for $16.79 for a hundred of them and I think it is well worth the price.

I have been using hairclips for years. They do an excellent job to hold the 4 sides of your quilt together, while
placing the top, batting, and background fabric together -- before you begin with basting. Followed by handquilting.
Hairclips come in various sizes which you can choose from.

I used to pin my quilt while binding. But, I got tired of getting pricked by the pins and I have animals so I have to be concerned with missing pins. I use both the binding clips and bolt buddies. The binding clips are a lot cheaper than the hair clips. In my opinion they both work great.

Just because you buy something from a "quilt" place, it is not necessarily better (usually just more expensive.) I buy hair clips @Dollar General and they work just fine. I can not tell any difference except, of course, the price! IMHO

I just started using the larger quilting clips and love them for holding binding in place to hand stitch

Use the hair clips and really like them.

what is the ladder stitch ?

I love the wonder clips. They hold very securely, and they also have 1/4" markings on them. They have them on Amazon fairly cheaply. I think they are well worth the money, I have even used them for other things in an emergency like closing a potato chip bag

I hope she knew how to get the rust out with Whink rust remover. Works great.

Also, the wonder clips have lines imbedded in them so that you can see how far away the seam allowance is extending. These lines are helpful. But now I don't use them as much since I found out about Elmer's School Glue.

Depends on the hair clips - I use both and I don't notice a difference, but some little girls hair clips that my daughter uses in her hair are very flimsy. Just pay attention when you're buying them. But when I bought binding clips there wasn't a huge difference between the price of the "real" quilt binding clips and hair clips, so pay attention to that, too.
