My oldest daughter had no idea until one day she asked me what it costs me to make a quilt. I explained the cost of QS fabric, patterns, thread, batting, sewing and quilting time and or money if you have it quilted. I noticed that she now takes much better care of her quilts that I have made for her.
I just try to remember that once I give something as a gift, it is up to the recipient to decide how they want to handle it. It is no longer mine, it is theirs.
I make a lot of charity quilts for my church and my 2 guilds and I find that I am much more joyful if I just look at the beauty of the project and not the cost or time. I just love to quilt and it does my heart good to just share my God given talents with others. :)
