Wow, I wish my nails looked as nice as yours do! Over the last year or so mine have gotten little ridges, thin and splitting all the time. When they do grow out a bit I have to trim them all the way back cuz they have 'snags' all over them.
I know some professional quilters who have extraordinarily long nails, I don't know how they do it, LOL.
warm quilt hugs, sue
