My second sampler for the stitch files is the buttonhole stitch. I use a big piece of 28 count linen and when it's filled with samplers, I'm going to attach them to the worksheets. This time I used stranded floss (Venus) and perle 5, 8 and 12. The size is 2 1/2 x 4 inch. Two opposite rows of Stef Francis perle 5 and a green row with perle 12.
