And for #5, however the list can go on. Coasters. The scrap bags I make are color coordinated so you can make a set of fabric coasters that complement each other. A great house warming gift or gift for yourself. Martha Stewart has an easy tutorial. These are quilted but you don't need to do that. 2 rows of stitching around the edges are enough.
Off the top of my head some more ideas are: ornaments, fabric flowers, glasses, buttons, barrettes, zip pouch, fabric necklace, kids belts, napkin rings, memory game chips. So many diy projects, so little time. But the fabric won't end up in the landfill. To buy some scrap bags you can visit my Etsy shop or email me firstname.lastname@example.org and I would love to see what you make! I find when given restrictions we can create so many interesting things.
Happy New Year!
