I have to say that I have really enjoyed making all the mini samplers so far. TAST I've liked all the stitches but I think my favourite at the moment is chevron. I am making some mobile phone pouches on dyed cotton using a variety of these stitches so when they are finished I will post pics.
On all these samplers I start off with a plain stitch to get the structure correct. Then I start doing variations, using the weave as a grid to figure out the pattern. On the sides I loosen up, getting off the grid and doing freeform work.
They are such great references for when I want to create a piece I just flip through these to the stitch I think will work with what I am doing. I just rec'd a bunch of Krenik metallic ribbon threads. Yummy. I like the idea of building up texture so I am thinking of doing another set of samplers using ribbons, yarns, etc.
