Welcome to the Quilting Board!

If I use a pattern or a version of it, I always mention where the pattern was from. If it was a free tutorial, I give the website.
Generally the entry form asks/ requires this information when you enter a quilt. The name of the quilt or information the ( viewer) sees does not necessarily show that information. Entry forms always require, if a commercial pattern is used the name of the pattern/designer - so credit is given.

If you have participated with any quilt competition, there is already a huge amount of information that is required to be filled out on an entry form. But i do agree, if I saw a pattern I liked, it would be convenient to have that info on the entry form attached to the quilt.

I have seen many at shows that stated the pattern and gave credit to the longarmer, and others. I say go for it. It will put you in a good light.
