Don't feel bad - I have both a cross stitch stash and a needlepoint canvas stash :oops: I have also been building my fabric stash for some years, though I have only recently got around to making my first quilts, lol.
Just dive in there and get started on that Bow Tucks bag, which is also on my list of things to do, btw. You will find plenty of help here, if you happen to need it :-)
