Three of the several fine quality table centres I bought, showng the range of colours, hard to resist. The thread is #50 sewing machine thread approx.
The very folky appearance given by these random colour combinations strikes me as having something akin to sampler quilts, on which I have been known to express strong views in some quarters…. and I did buy one coffee and creme coloured one.
These mats are approx 25cm across. 
These are such a wonderful respite from white lace. I can see them scattered on a table with white dishes so that nothing distracts from their luscious colors!
