"Grandmother's Flower Garden"

When Jack & I got married, his grandmother gave us a set of tea towels embroidered with different fruits. I have long thought that they needed to be preserved in a quilt/table topper/wallhanging of some sort, and had been thinking of using 30's reproductions, but I never had found anything that I really liked for them pattern-wise.

This spring I went to the Missouri Quilt Guild show at Powell Gardens and saw this kit using pre-embroidered baskets in a hexagon log cabin setting and I knew I had found the pattern for me! I haven't yet done the fruit towels, but here's the kit I purchased and put together so I could try my hand at the weird angles before cutting into Jack's grandmother's handiwork. (BTW I found a GREAT video tutorial on machine-assembling the hexagons on YouTube - of course I forgot to save it... but it's there, I promise!!)

Now I need to tackle G-ma's fruits, but there's only 6 of them... any ideas for a center block since I don't really do embroidery?
