Absolutely impressive! Being that they are such small blocks any distortions can really show up. Your blocks are all perfect.
Here's a few questions:
Do you use a lot of starch on your fabric? They all look so crisp.
Are any of these paper-pieced? I didn't quite understand the part where you said you cut the pieces bigger.
Where did you get the patterns for the blocks and the bears?
Any other secrets you can give us?
Thank you for sharing your wonderful work.
