I found the bells at JoAnns along with some mini jingle bells.
This one I used 6.5" square fabric, midweight interfacing and lining. Stitched, together leaving about 3" on one side for turning. Top stitich around edges. Fold in half (end up with a rectangle) Marked about 1/2 to 5/8 inward on the fold, and another mark about 1.25 up the side and stitiched point to point for the taper on each end, then folded the other sides and stitched again.
I've also done this using 10.5" squares and stitched up the sides 2.5" and taper to 3/4 on the fold.
I made a smaller one about 8.5 and just a slightly smaller taper (don't remember what I did for this one!)
Cute baskets and everyone enjoys receiving them!
