Kittywolf13,
My "Whacky" bags and machine covers are basically scraps cut into 3.5" squares and stitched together.
The bags have 83 pieces, the machine covers will vary.
For Louise's cover I sewed the front and back together separately then sewed the top in. After that I stitched on the very stiff Pelon interfacing and then the felt insides. After trimming all the edges I sewed them together right side to right side up each side and then the top. Then I put on the seam binding and turned it right side out. And I have to say I'm rather pleased with it. It's one of the best projects I've sewed so far.
I made a cover for the folding plate on our Featherweight too. I'll do another thread on that one in a bit.
