I do not join swaps. Two years ago I joined my first swap.
The triple 4-patch was the block, they were 6 1/2 inch blocks. Some blocks I received were smaller, I couldn't use them in the quilt. I can't imagine that the persons sending them didn't square them up after piecing and realize they were too small. Some blocks had fabric so thin you could see through it. And I couldn't use them in my quilt. And one set of blocks didn't follow the color requirements. Which was a light/dark 4-patch necessary for the design pattern. So they could not be used in the quilt. Out of 14 blocks I received I could only use 6.
So I threw away more blocks than I was able to use.
I had hoped for a positive experience. Instead I was burned.
I haven't tried a swap since.
