Look into inklingo. You print the pieces and seam lines on the fabric with your inkjet printer. Cut them out and sew together. She has a number a different patterns you can choose from. You could print a few pages out in an evening, then cut them out another evening. Just a few minutes per evening, maybe 30 at most, for a couple evenings and you will have your pieces ready to go.
As far as scissors for thread, some needle threaders have a thread cutter built in.
