I made this patchwork using 100% cotton bleached muslin. It's all hand-sewn. You can use it either vertically or horizontally. The plant-based dye has been colorfasted, but when washing, please use a neutral detergent (like Emal) and wash it separately from other items, and dry it in the shade. As this is a handmade item, it is not perfect like a mass-produced product. If you like it, please consider purchasing it. * There are some areas where the blue chalk pen marks are faintly visible, but they should disappear after a few washes. * It has been ironed, but it wrinkles easily. * It will be shipped folded. * Shipping will only be on weekdays. * Recycled materials will be used for packaging. Item No. 005
