The last couple of Sundays I've been using fabric precuts to inspire you, so this Sunday we'll keep going with layer cakes. You can find the SQI post on charm squares here and the SQI on jelly rolls here.
10" squares are large enough that they can be cut down to any size that is at least ten inches. They are especially good for making disappearing patch quilts, such as disappearing four patch or disappearing nine patch.
