My daughter and I tried 'MyStuff2' for the iPhone but we were unhappy with that app. We were updating the database and lost a bunch of pictures we had taken. She then found 'Airtable' and we have been entering our stuff into that and its free. I think it is going to do the trick very nicely and its very versatile. It is web based so you can share database info with others if you choose. You can add pictures, so we have pictures of the front of the pattern and the 'Materials Needed' cuz it always seems I find great fabric for a pattern but can't remember how much of what I need for it, lol. And if/when we get the project done we can add a picture of the finished item. There are about 4-5 of us and this way we know what patterns we all have if we choose to borrow patterns or ask questions.
