Needle turned applique... I am about to start a Hawaiian wall quilt and it has lots of needle turned applique. It's portable because you first baste the pieces on the background so you can carry it around without any pins in it. All you need is sewing needles, thread and small snips and you are good to go.
There are lots of lovely pillow patterns or you can cut your own using the "folded snowflake" method.
