I think with all her volunteers to help it could be done is about a month, 2 weeks is going to be stressing the OP greatly. But I'm sewing my 4 patch scrappys this morning and hope to get them in the mail this afternoon or tomorrow morning.
I hadn't thought about her DIL having to do the other 6, if she's a new quilter she may not be doing intricate blocks, maybe just big squares.
Do you plan to quilt or tie these?
