Lee -- you will be so happy when you are on the other side of this project. I just can't get over what a difference the scrapbox makes for me. Gone is all that frustration that happens when you can't find your stuff. You know you have it but can't imagine what where you hid it! I can't tell you how many blades I found for my trimmer - I'll NEVER have to find those puppies again LOL!
Good luck -- I hope you'll share pics when it's done. So cool that your FIL could make something like that.
