LABELING MISTAKE ON THE VIDEO WITH THE BLOCK.
The video shows Letters on the Fabrics for the Background Block and Numbers for the Pieces. MIX UP MISTAKE.
Follow the Instructions in the WRITTEN PATTERN for the Block using NUMBERS for the FABRICS and LETTERS for the PIECES. The video still shows the how to, just ignore the numbers and letters.
SO SORRY FOR THE CONFUSION. What happens when you do the pattern and the video at different times.
