You can use the spray fusible but be careful that it does not discolor the fabric you spray it on. I was using Sullivan Spray at the time and is turned my white fabric yellow. It never did that when I sprayed it onto the batting but it destroyed the white on white fabric I used in my embroidery and it did not wash out. I wrote to Sullivan and never got a response - I was hoping they could tell me what to use but never responded.
When a friend needed to make a flag with satin-type fabric we used a two sided stick on stabilizer - she was able to draw the design on the paper - then stick it onto the fabric cut it out and then peel off the other side and stick it where she wanted it. There was no ironing involved.
