I can think of hundreds of reasons to make a bag. I can think of hundreds of things that I could put into a bag. A yoga mat, for me at least, is not one of those things. But of course, the project for January 4-6 was from Bored and Crafty and was originally designed to carry a yoga mat.
I followed the original directions to measure the length and circumference of my carry-able object then cut and sewed my pieces just as described. My bag was obviously shorter than the original, taking up only a fat quarter for the outer bag and another for the inner bag. I also omitted the strap used to carry it over my shoulder which saved some additional fabric. I fused some lightweight interfacing to the lining fabric and double interfaced the bottom for stability, but ended up with a bag that almost stands up by itself, so looking back I didn't really need to add that step. I also folded, stitched and pressed the opening of my drawstring casing as an added precaution against frays.
With more snow in the forecast tonight, this baby will be making it's maiden voyage to the office tomorrow.
