First, I am fortunate that both my niece and her daughter are interested in quilting and will take most of what I have. Any duplicates of tools, etc., they have promised to donate to a quilting guild so they can be given/sold to members, hopefully.
Second, I am moving in the summer to central Texas and am starting to go through all my UFOs and other projects as well as fabric, tools, rulers, templates, etc. The cost of moving all that is something I don't want to even guesstimate. I will have them look at the "go away" pile and take what they want and donate to a guild or give to a thrift store the rest. Or maybe post it on my neighborhood web page.
I have really tried to hold back on buying anything new but there are some things that have crept in. But as I go through stuff and realize how much I do have, it is easier and easier to resist the temptations!
