This was my first time pp and I was looking forward to it after watching a couple of videos on it (just search online or YouTube). The test square itself was eye opening for me as I realized that I need to make sure and check that when I iron back on the seam that the fabric reaches to the SA outside the block I'm working on. I did have to rip out a couple of seams at times. Another one of my boo-boos is that I'd jump to another number out of sequence, thinking I could make it work. That doesn't always work and so ripit I would go!
In the end, I do like pp but it does take some getting acquainted with the orientations. I was not only inspired by Sulabug's House of God choice, but enjoyably challenged! Thanks Sula!
