This square pillow is from my new sewing pattern, Mod Flower Pillows, and used one of the competition trimmings packets, together with some solid color fabrics in shades of peach and orange. The rules require using the trimmings in any creative way; other fabrics can be used as long as the prints are the focus. The trimmings pieces were kind of tiny, at most 5 inches long on one side:
It has an envelope-style back for easy insertion.
The little rectangle pillow below is also from my Mod Flower Pillows PDF pattern, which is for sale on my site here and in my etsy shop. The pattern has instructions for two different pillows with cute retro flower motifs, which can be appliqued in felted wool or quilting fabric. The templates are full size.
I used a machine blanket stitch for the applique, but it could also be done by hand or a zigzag or running machine stitch.
