I gathered my supplies: Red polar fleece, a denim fabric with glittery stars, white and blue felt, various colored threads and some buttons.
I measured the back of the chair, and cut 2 pieces of my polar fleece only slightly larger. I used polar fleece for 4 reasons: 1.) it's stretchy, 2.) it doesn't fray, and a raw edge is fine, 3.) it's soft and 4.) it wears well.
I cut out the words "I am a Star" directly from the white felt. I printed my own star pattern off of the computer and pinned that to a piece of blue felt. I used felt (again) because it doesn't fray and a raw edge is fine.
After a few layers of felt, denim and polar fleece, here are the results. Notice how I used pinking shears on both the polar fleece and the denim. This adds yet another layer of interest, and prevents the denim from fraying. I handstitched the letters and the star to the layers of denim and polar fleece. Then I machine sewed the two layers of the polar fleece sleeve together on 3 sides. I made sure to heavily stitch the bottom corners, near the opening, as these will be the seams that get the most stress. The teacher was thrilled.
The sleeve easily slides over the top of a kindergarten sized chair, and can be moved from week to week. I really like how all of the layers, different fabrics and buttons add texture and dimension. The bright colors make it cheerful and eye-catching.
I was thinking these would be a great addition to a holiday table. Felt pumpkins with a few sequins, or Christmas trees with button ornaments would be beautiful. You could also make them for your everyday kitchen table. Maybe put the kid's names at their chairs. How about a special "It's My Birthday" sleeve that makes the rounds for each member of a family? If you make one, be sure to link back, I'd love to see what you've come up with!
