Hi Rhonda,
I place the edges so the fabrics match if needed. Fold one edge under half inch and place on top of the fabric so the patterns match.
Use basting tape or wash away tape to hold them together. Lay the fabric right side together and then trim to a half inch seam allowance. I draw the seam line and stitch down the line. Press the seam line. I use starch along the seam.
You can trim the seam down to a 1/4 inch if you like.
I also top stitch the seam line so it doesn’t flip when quilting. You can always take it out later after quilting if you like.
