Some organizations are picky. One in particular will return quilts if they are not made of quilt shop fabric. They suggest you have bake sales and such to raise money for this year's fabric lines. That is totally unrealistic in MY world, so I bring any quilts for veterans directly to the VA hospital, where they have always been graciously received and distributed.
I am sure whoever is using yours is not obsessing over the construction method. You just need to connect with the group that appreciates your efforts. Sometimes the most well-publicized group is not the best fit for everyone.
