Oh my goodness, I am so sorry that any quilter of any age would make you feel unwelcome. The only way quilting will continue as an art form is if older women and men teach younger women and men how to quilt. I belong to a Tuesday morning group at my quilt shop that is made up of women of all ages (and we've had one man join us occasionally). We learn so much from each other because every one has different eyes for fabrics, colors, quilt patterns, etc. Keep looking for a group that you feel comfortable with and feel comfortable sharing with.
