This is the second block I've done for this QAL, but there are already a total of 3 free paper-pieced Doctor Who patterns so far provided by Soma and Caroline. There will be a total of 20 when the QAL is complete. They are 12" finished blocks though I have been finding mine to be closer to 12 1/4" than the 12 1/2" needed as I finish paper piecing. A bit small...
You can find the pattern here.
I was initiated into Doctor Who with number 4, Tom Baker, so I needed to include K-9 in my quilt, for sure.
These blocks are challenging, I think but do-able as long as you take it slow...mine are not perfect but I am happy with them and my son seems to approve as he expects this quilt to be his.
