I had the same thoughts before reading everyone else's posts...The 3 x 6 is more 'standard' and traditional, while the 4x8 would be a little more unique and bring a modern or industrial twist or zing to your kitchen...which I can like with traditional elements. Depends on what you want it to do. And Plllog does have a point about smaller tiles fitting in around things better, but I wouldn't necessarily let that decide it for me. Will one fit in the spaces using whole tiles, while the other will require cutting all the way along? (Remember to figure in grout lines) Even if I liked one better, if the other fit in whole, THAT could sway me to change my mind.

I went through this as well (before I changed the whole blasted thing) and the consensus I got was to vary--if you have diagonal on one, do straight or running bond on the other. But if diagonal makes you happy, do what makes you happy.

I'm not sure how I came across this post, I think it was displayed on the right side and I clicked on it being intrigued by the tile making. I was at one time interested in working with papercrete and hypertufa. But after enlisting my brother, who wasn't as enthusiastic, and my niece, who poured cement down my laundry room sink, which original to the house had lasted 70 years, and ruining three blenders, my interest waned. True to form, if I come upon difficulty in a project, I think of it as a sign for me not to continue. And really, after all these years of trying various crafts that result in crap, I should know better. I also should have known better than to ask my brother, who always says it can't be done to any of my unique design ideas. And I should have known better than to ask my niece, who once stayed up all night before having to drive to LA for an art show, cutting mat after mat after measuring once, twice, sometimes ten times, but always coming out with the wrong size. I think we both have math dyslexia. I should video us trying anything crafty to see where we go wrong. I think both of us having ADHD might have something to do with it. Sorry for the backstory and run on sentences. So, I just wanted to see if you continued with your venture. And to say sorry for whatever tragedy occurred to cause you to have to move to Florida. Not that there is anything wrong with Florida, but it isn't Panama. Which is one of my favorite places in the western hemisphere. I hope no one is upset that I brought up a seven year old post.

Thanks all. The main thing I had to decide on was size (not color) so made a 2x6 & 2x4 basic wireframe pattern in Microsoft Excel, printed lifesize and taped together a few to get a sample poster to put on wall. This let me get to 2x6 as choice - it didn't seem too skinny-- if anything 2x4 seemed too small for a kitchen (personal choice). 2x6 might also make things less busy if you have multi-color and that's a concern. (Noted that layout detail such as near kitchen window and grout color are very important.)
