Help needed creating one or two quilt blocks

My nephew is getting married in April and his sister has invited me to participate in a "wedding quilt" project. She would like family members to create one or two quilt blocks in the log cabin style that she he will assemble as an heirloom gift for the couple. Although I am an experienced sewer, I don't feel very confident in my quilting skills. I am looking for someone who can either cut and assemble the blocks with me or for me. I would supply the fabric, so even if I am not actually doing the sewing my contribution could be in designing the color patterns in the blocks. Let me know if you would like to be a part of this project! thanks, Ellen
