I put up a a picture of this project & someone asked for the pattern - it was a kit that someone bought me at a quilt store out of state - there's no info on where it came from and no copyright info, so I assume its ok to share. Wish I could give credit to whoever created it, but I have no clue!
I have no idea if you are supposed to poke holes in the potatoes before cooking in this bag...it doesn't say to, so I'm thinking maybe not, but I'd be nervous to try - the one I made, I just gave away as a gift and I am waiting to hear how it works out. :-)
Here are the directions exactly as printed:
BAKED POTATO BAG
Use this bag for a well done, most potato. 1 to 4 potatoes. Wash, wrap the potato in paper towels and microwave your potatoes following the instructions of your microwave manufacturer.
1/2 yard Fabric
9" x 21" Cotton Batting (the batting in the kit looked like that really thin Warm N Natural stuff)
Step 1: Cut 2 pieces of fabric and one piece of batting 9" x 21".
Step 2: Lay fabric right sides together. Place batting on top. Sew across the 9" ends witha 1/4" seam.
Step 3: Turn right side of fabric out with batting int the center. Top stitch about 3/8" along the stitched 9" edges.
Step 4: Fold one of the 9" edges down 2 1/2" and fold the bottom up, overlapping the top by 1". Fold in half and sew the side seams.
Step 5: Sew the long side seams together using a 1/4" seam, stitching through all layers. Finish these seams by serging or zig-zagging. Turn right side out. It is finished and ready to use.
