Kensington and stitchpost you may want to look up Boom 7 groups and look at their albums and see the members blocks they received. This might give you an idea because every fabric that you receive will be different fabric, then you choose what block to make and what fabric you have that will blend with that person's fabric, unless they have included a note and said please only use yellow and green, my background will be white. that way stitchingpost has sent everyone the purple fabric for an example. And keep in mind that you may receive a similar request to only use a certain color or to please not use a certain one. If you look in my albums received are the ones that I got back, I sent out the fabric that has the pottery pots. albums sent are the fabrics pieces I received from the other group members and this is the blocks I made from their fabric and returned to them. Hope it helps you, just trying to give suggestion that may make it a little easier. Hope you have fun with this.
