I have not made the quilt, but it's on my bucket list. Are your triangles the correct size? The two black on the right and the grey on the right don't go all the way to the corner of your strips. On the right strip, both ends and on the white strip just left of it, the top black triangle.

Does anyone know which issue has the corrections in it? QUILT magazine pattern Labyrinth Walk Apr/May 2012 has some mistakes?

they usually have the corrections on their site.

I seem to have the same problem...we’re you ever able to resolve it?

if you have purchased the pattern within the last 2 years you should be fine. My pattern was. I did not have the magazine pattern version. Check the the pattern website website for the corrections
