Either would be fine. A word of advice from someone who uses that stuff A LOT, make sure you machine stitch your pieces to your background fabric if this quilt will be put in the washer and dryer. the fusible beats needleturned any day but is not necessary permanent when put in the washer and dryer. Also if you have any decorative stitches on your machine, consider using one of them where the "corner piece or curved piece, meets the ribs of the fans. Especially in contrasting thread. Just a suggestion.
