So sorry for your loss. I have to stay organized or my creativity vanishes! Separate each craft into clear plastic totes if you have them. Big boxes will work for a start if you don't have totes. Once you get them separated you can start organizing each craft. Picking out the right storage containers or furniture can take awhile. Just get things separated for now, then you can decide the right storage for the type and volume of each type of craft. Don't try to do it all at once. Take one step at a time.
