Depending on how much yarn there is to spare, more than just a few can be used to edge a lampshade or a poncho in one colour or a rainbow of colours.
Why not attach several to a clip and slip it into your hair or wear on a hat.
A bunch of twirls on a wrapped present is an unusual, pretty embellishment which can be used by the recipient or passed on again by being attached to another parcel.
Several twirls also look attractive on a basket as well as on a suitcase which is where my very first twirl still lives. I found that my suitcase was being mistakenly taken from the airport carousel before I could claim it and so I gave the case an unmistakeable embellishment, a twirl. It has remained in place through many airports and its success began my TWIRL addiction.
If you have ideas for TWIRL usage do let me know.
Have fun making.
