make a list of all the new fabrics or other sewing supplies you want (this is a list that will change daily but just keep adding as you see something you really like). Then when ever any of your family asks what you want for (birthday, all holidays or special occasions) just point to the list and tell them pick one or two or even the a dozen.
I get so tried of hearing my kids say they can't think of anything to buy me for (whatever) because I always buy what I need for my self so this list thing sure has put an end to that statement.
