Well, I sew ... so ... I guess I will make them.
Back to the computer for bargain fabric. I found outdoor fabric at fabrics.com for $9 a yard and using a 50% off coupon at JoAnn's I bought an entire box of NU-Foam (the special batting for outdoors) at half price, about $10 a yard, bringing my cost to about $20 per cushion. Plus you can see the fabric will really help the table look like it goes with the chairs.
