Personally, I don't like others telling me what my "ministry" is. I'll know it in my heart. It seems like in your heart you want to do this so great! My only recommendation is that you pick a pretty simple quilt pattern.
I "taught" a good friend last year, how to make Christmas placemats. Knowing she was inexperienced, I designed what I thought was simple pattern, 4" squares of different Christmas fabrics. I didn't realize how difficult it is for a novice to even use a rotary cutter! And sewing a straight seam was a challenge! She used my Bernina machine and I sat right with her, guiding the whole activity. Some of the seams were 1/4" and it wavered to about 1/8 up to 1/2". I didn't correct everything unless it was a problem when she turned it. It was an education for me--teaching inexperienced folks! I strongly advise to use a simple pattern! :)
