I just did the A1H10 block and it's really very pretty. Block A1H11 is just a flipped version so no video for that one.
This block is heavily embroidered at over 30,000 stitches. You will need fabrics 1, 4 and 3, water soluble thread and threads A, B, C and D. The only issue I had with this block was that my thread A and B are fairly similar in color so when they're next to each other you can't really see any difference but that's okay. Overall, it turned out really pretty and I can't wait to see the next one.
I did add stabilizer to Fabric 3 for this block. There's a lot of embroidery on Fabric 3 (the pink fabric in the picture) and if you don't add some stabilizer, it may wrinkle or pucker as its embroidered. I used Sew Lazy soft lightweight stabilizer and it worked just fine but use whatever you like or have on hand. There's a lot of thread changes making this 57 minute block turn into an hour and 25 minutes. Remember, you can see all the videos for this quilt on the Hoopsisters website.
