Here is what I was able to find about the fabrics starting at the upper left corner. The first fabric is a home decor weight (twill, 100% cotton) from "Project By Cotton". I love the floral print. The soft colors would fit perfectly in my living room. I guess that is why my sister picked it. The second is linen/cotton blend. It is from the Dutch Door Press collection by Letterpress & Design Studio for Kokka.The third I cotton hemp canvas named Polish Nostalgia also made in Japan. These cute small prints would be ideal for small projects like pouches. Unfortunately, there is nothing written on the selvage of the fourth print. I wasn't able to find anything similar. I think this large print will be perfect for a bag. The last fabric but not the least, is a print designed by Kayo Horaguchi. I didn't know this designer, but her whimsical illustrations are so pretty. And I just love the colors of this one. The warm pink, orange and yellow on the neutral background. This is printed on double gauze cotton.
The print by Kayo Horaguchi is definitely my favorite. I'm don't know yet what I'll do with it. I can hardly imagine cutting into it. I saw some people made some nice little girl dresses with her prints (here, here and here). But, I have two boys ... So, maybe something for me. Maybe something like a Washi tunic. I don't usually sew clothing, but I thought that would be a great occasion to do so. I'm not sure I have enough tough. I'll probably need to combine it with something else.
The best part of getting new fabric is really having to imagine all the possible projects. Thanks again Isabelle. What a great souvenir from Japan!
