Hey Grasshopper - welcome to the Board from Minnesota! I think you may have bitten off more than you can chew at this point in your quilting career; I think we all do. Your fabrics sound great - it's nice to have a theme. Your Singer will be just fine - I use a 40-year-old Kenmore for all my piecing and free motion quilting (FMQ). I also use my dining room table - lay your top left corner in the top left of your table and work across and down from there. Support the other parts of the quilt with the backs of chairs. Use basting spray - it will keep your layers together much better and with a lot less work. YouTube has some great videos on how to quilt larger quilts on a regular machine like your Singer. I'm so excited for you just starting out - do post pictures of your progress so that we can cheer you along.
