I wanted this cape to have two shiny satin sides, and then a sparkly outer layer that was loose and 'flowy' (you know ... for all that twirling a Queen must do). To accomplish this, I first sewed the outer sparkly fabric to one of the satin pieces around the neckline only. Place one of the satin pieces right side (shiny side) UP. Place the sparkly fabric on top (right side UP), match up the necklines, and pin in place.
Sew these pieces together along the inside of the neckline only (using as small of seam allowance as possible ~⅛).
Now, place the other satin piece on top of the sparkly fabric FACE DOWN (shiny side down). Pin along the inside of the neckline.
Sew along the inside of the neckline again, this time attaching all three fabrics.
Next, pull the sparkly fabric that is sandwiched between your satin fabrics away from all the other edges (you are going to sew the satin pieces together in a minute, but you don't want the seam to grab any of the sparkly fabric).
Pin the two satin layers together around all edges (with the sparkly fabric inside ... bunched up away from the seam you are about to sew).
Starting along the bottom of the cape, sew around all the edges, but leave a gap (~3") along the bottom to allow you to flip cape right side out in a minute (backstitch when starting and stopping sewing).
FLIP! The best part (in my opinion)! Your cape should now have two shiny pieces on either side, and a 'flowy' sparkly layer on top.
Iron the seam on the two satin pieces of fabric down all the way around the cape.
Sew a top stitch all the way around the two satin part of the cape. This should close the gap (make sure edges are tucked in when going of the top of the gap) and cause your cape to lay more flat.
Sew on your velcro pieces to the edges of the cape neckline .... easy access for those 3 year old hands!
