I agree with Gran of 6. Wow, they're awfully picky on the style of quilting for a donation that easily adds up to $300. They are shooting themselves in the foot. They get too restrictive and they'll lose out on some great donations as the quilters will chose other charities to deal with. They will also form a reputation that will hurt them sorely in the long run. It's a shame because it's the very people they are (supposedly) trying to help that will pay for that elitism.
On the question of whether you're a lesser quilter for using pantographs. Heck no! Are we less than for using rotary cutters rather than scissors? Fancy rulers rather than newspaper templates? Machine piecing rather than hand sewing? Decorative stitches rather than a straight stitch? Tying a quilt rather than stitching it? Freezer paper piecing rather than English paper piecing? Using a longarm vs a DSM? It's another tool and technique. I think there's room for all of it. Each method requires skill and they all produce amazing results. Be proud of what you do. Remember that those that sneeze at it probably wouldn't be able to do it themselves in a million years even with all the tools, materials and a handbook. That's why they find it so easy to judge.
