TSM Floor Flagstone 2

TSM - The Sims Medieval - has the prettiest textures for floors and walls. 

Here is a Flagstone floor, six swatches - Four-Sizes-In-One

Four-Sizes-In-One means that you can find them all under the same floor in the game catalog - you can see in game that there are 4 x 6 swatches, so each color has 4 pattern size options.

Mix and match, make decorative floors anywhere! Medieval but can really be used in all eras, timeless!
