OK - I have been playing with this! I really like the HST in the Irish Chain - I am thinking that this would be a great alternate block in a baby quilt! So this is what I played with ...
Assuming that the Duchman blocks are 12" square the blue HSTs are 1' finished (pretty tiny for my likes) so I went back and made the HSTs 2" finished in the green rendition. I like both and have saved both in my EQ lol!! Hope this helps.
