According to the instructions, this block was the "easiest" followed by the block with the pink center and then the flying geese block. I didn't notice that any one was easier or more difficult than the others.
I love the colors and even though it was a challenge for me, the blocks are perfect, which I don't get to state very often when I'm piecing. The next 3 blocks are also foundation pieced and even more complicated.
I'm going to wait start any more blocks as next week will be busy with out-of-town visitors and the beginning of our 4th of July Celebrations. For you followers that don't live in the USA, the 4th of July is when we colonists celebrate our independence from England, over 200 years ago. It is a big deal here in the States with picnics, parades and fireworks. Our summer town has a year-round population of about 20 that swells to many thousands next week. Last year we were all evacuated due to the threat of a nearby forest fire and the events were cancelled, much to our disappointment. We are all excited about the festivities next week.
