Here is block 4 of the Fat Quarter Shop Mystery BOM. My first thought when I opened the package and looked at the block, I noticed that it wasn't a basket. The first three blocks (see below) were all variations of an updated basket pattern. I am making an assumption here, by thinking this block and maybe a few more, will be the alternating blocks between the basket blocks. Oh, wait a minute, it is called a "mystery" BOM. So, I guess, we will have to wait until each month and see how this "mystery" plays out. That is part of the fun of this program that they offer each year. You can find out more about this BOM here.
Here are the prior month's blocks:
