Excel file fits swap(s) information: Name of Swap, host, due dates, addys, results, reminders, plus it can count approximately how many squares (1.5", 2", 2.5", etc) you have in stock to start/finish a quilt. You can measure how much you are spending on swaps: fabric, mail, baggies, etc., which is great for forecasting future swap budgets. Highlighting current or completed swaps keeps you on track & gives you an activity history. It is a time saver because it features 'books' in one file: swaps, stock, budget, work in progress, wish list, sale dates, shop hops, classes, etc. can all be found in one file name so you don't have to search all over the place for the information you need. I call mine Excel Quilting Books. You can even retire a 'book'. Envelopes keep receipts tidy in the event you need to reference them which is my only paper trail. A computer in my workspace is a blessing on so many levels. I hope this makes sense!
