That is sooo exciting. Think of their mental reactions to the designs. We have a lady who was seeing all of her life and lost her vision due to MS. She is a avid quilter and operates her old Singer sewing machine. Someone threads it for her but she sews her blocks and her quilts are very nice.
Havingbeen sighted, she has an advantage. She picks fabrics
by feel and someone helps with color so she knows what color has what feel. Its fascinating.
