This is block 7 in Susan’s stars and pinwheels quilt-along, called Expanding Star.

I’m using these blocks-of-the-month to make a different project each month rather than saving them for a quilt. This month, I reduced the block size to 8 inches (unfinished) and made three of them to incorporate in a table mat for a special table in my living room. I fussy-cut three designs from a Christmas panel and added some festive fabric to make the red diamonds.
I bought the vintage sewing table in an antique store several years ago and it gets constant use as a table for sewing, eating, watching TV, working with photographs, writing notes and cards, and is the regular Sunday dinner table for my reclusive 16-year-old grandson. I keep a mat on it at all times
This is an easy block which has a good secondary design.

Love what you did with this, Lillian! The fussy cut centers and the Christmas look are just perfect. Thanks for sharing it.
Nice and bright and cheery–love the center squares
I love the bright colors! You always do such fabulous work – Kelli
Your description of your vintage sewing table makes me wish that I had one just like it. I need to a small table for my various little projects.
