Rosehawk,
Here is my "All Machines Denim Quilt" top. It's a queen size using denim scraps from my wife's projects. I used almost every machine we have to do either piecing or decorative stitching on it. From my 100+ year old Minnesota to our early 90s vintage Singer 4622a, most of the machines got a bit of a work out.
It took me over a year and a half to cut out, piece, decorate and assemble the top.
Here is a pic of the matching lap quilt top:
The backing is not on the big quilt yet as my health has been lousy the last year and a half and it will take us moving the 201-2 outside in the driveway with tables to put the back on and quilt it.
So, take your time and be careful with your seams and stitches and you'll get it done.
Joe
