|i downloaded an app to my ipad to keep track of all sorts of things. its called Bento, does not cost a whole lot but its quite powerful to keep track of all my sewing patterns particularly. i take images of all the envelopes, create different inventories ie. vogue, butterick, burda etc, give each pattern its name or number, description & notes ie, when i sewed the item, how long it took me etc.
i also link directly to the pattern review website page of the pattern so i dont have to search for the page every time! saves time &everything s just a click away.
this way i also have it sync'd to my iphone so i can take the info with me everywhere..ie. when pattern shopping i can avoid double purchases, know meterage required etc.
highly recommended not only for sewing but any inventory, expenses, tasks, notes etc.
check it out!!
