I have had a few questions about Aprils instructions for our Mystery quilt project so thought I would post picture to help. Above is the work from April's instructions and you will have 64 units ( 42 for smaller quilt) in each pile.
Below is a photo of what you will have leftover after finishing Aprils instructions. You'll have 64 (42) triangle units and 64 (42) HST units ( from bag A) left that will be saved for May's instructions.
Hope that clarifies any of your questions. There are no errors in the instructions so make sure you follow the numbers required for each step.
Can you guess how many blocks this quilt will have? :)
