I don't like using the pins to baste because I feel like they add a lot of weight to the quilt.
I agree I love the 505 spray - but it gets expensive for me.
I have started to use the elmers glue and that is my current basting option. I have used it on small and larger quilts and I am happy with it... but I do still end up with blobs of glue so I wish I could get better at applying the glue
