Accessories are an excellent project to make a hand-made outfit look custom. They are also a great idea for beginner sewers because you don't have to worry about fitting issues.

My daughter reads many books on her kindle and here is a cute pattern to make a cover or case.
|Violet Fields Threads' Felicity hair flower|
|Violet Fields Threads' Delilah necklace|
|Burda Shoulder bag|
|Burda Soft Satchel|
And I just love this rose necklace from Violet fields.
And several pattern makers have a wide variety of bags and backpacks that you can customize to fit the needs and fashion sense of your tween.
And what about accessory tutorials? There are a million free tutorials out there with some great ideas for accessories. Simplicity has several HERE, and I thought THIS recent post on Sew Country Chic could easily be translated for a tween.
