If all goes well when making these beauties, the outside quilted fabric should measure 12" x 9 1/4" - but if you are little off by a 1/4" or more (like I was) just make sure to cut your lining the same size as your outside piece. Then everything will fit and match perfectly. Still cut the corners the recommended size in the tutorial.
I experimented using fusible Pellon 906F Sheerweight interfacing on the lining fabric to see if that made the basket a little sturdier. It did, although turning the basket to the right side through the lining was a little tight ... it was worth the effort. (see above)
This basket using Amy Butler scraps is made with batting only and no interfacing - it holds it's shape and is a good one to start with to learn the process.
I used a #12 needle and regular sewing foot throughout. No need to use a walking foot but slow sewing to attach the handles is prudent. Aurifil 50wt thread is a winner as always - as is using up scraps & extra batting.
