I do hope you give the guild another chance. It can be such a great opportunity for sharing and friendship and learning and giving.
Totally agree with the others - the people running the organization make all the difference in whether the group is welcoming or not. Another side of the equation, it is usually the same core small number of people doing a huge chunk of the work to make the whole group function. Would you consider offering to help with one of the committees or work groups? That would give you another opportunity to get to know the guild members better.
I have found so often that most people are just trying their best to have fun and enjoy their quilting. And I'll bet that if you share your work (does your guild have a "Show & Share" segment?) and talk about why you made the quilts and who they're for, the guild members will appreciate your good heart - sometimes knowing the story of the quilt gives you an entirely different take on its beauty
