The slab for May is crazy piecing, a great opportunity to use some of the scraps you have created from making the slabs from previous months. For my crazy piecing slab, I started with a four or five sided shape and added strips and chunks of fabric until I had pieces the sizes I wanted.
This tutorial from Victoria Findlay Wolfe is a great way to get started on this crazy piecing slab.
The May slab needs to be approximately 15″ x 30″.

Hi – just wondering if the June block guidelines will be going up soon? I have been following along from New Zealand, and really enjoying the monthly improv experiments.
Hi Heather, it’s so great to hear that you are following along! I’ll try to get the June Slab instructions posted in the next couple of days, sorry it has been a bit delayed.
