I helped my aunt do something similar - Each year at their family reunions they auction off a quilt from previous year. My aunt doesnt sew and has to have the majority of it done by othrs. The year I helped her we took a picture of her granparents wedding picture and their original homeplace and put that in center - she then asked the LQS what size blocks she would need for each family decendent. I then did "scrapbook" type pages with each family's pictures and used the three main colors for matting etc on the "page". Also had to incorporate that families name in square - some were a breeze since some didnt have too many members - others had almost too many to even fit on page!! I used my scanner to copy and size photos.(everyone wanted original pictures back so I could cut them!!) I had to make sure the blocks were uniform and put the names in center to start and alternating the colors.The names were all done in the darkest color and the matting etc done in the other two - all I had was the fabric to match papers to. Any way to make a long story short I didnt charge my aunt for my labor just the materials. I ran all over twon trying to match the colors to the fabric. But she is my favorite aunt (She was married to my dads brother and they were divorced but shes Still and always will be Aunt Jane)sd
I was ask by lqs owner what I would charge pr block if others wanted it done (I may have priced myself out of a job but for a appro 15 x 14 square I quoted 25.00 for labor. It took alot of time to figure out sizes, colors etc. not to mention the gathering of pictures and copying just the pictures then the time to verify the pictures and people with my aunt for accuracy. (It was for her moms side of family so I wasnt familiar with any of them!!) Much harder to do when you arent familiar with names and faces!!! The LQS then took and copied my "pages" onto fabric. The quilt turned out great and they actually made a little money on it so she could begin to do one for the next year!!!
So hear are my thoughts - its hard when you arent familiar with names faces etc.
I would have them have pictures and names done at a lqs
let them know how much fabric you will need (let them furnish it) Each family heritage may not fit into a layout as nice as yours did so it could take alot more time to figure out placements.
These will not be a labor of love like yours were!!! You will fret and worry more if its for someone else.
I think in the long run I would just say no lol If you want give them a pic of yours and let them go to a lqs to have one made. lol
It is such a beautiful quilt and what a great gift you have given your family !!!
You have inspired me to finish the scrapbooks I started 10 years ago for each of my sibling (yeah in my spare time lol) Needed to do 5 but did 6 so both of my kids would have one of their own.
Good luck in your decision.
