Chie-sama, Thank you very much for your bulk purchase. Thank you for your patronage. I've created a natural cover by combining Bubble Bubble (DeCollection) with linen, lace, and embroidered fabric. This is from the Nuno Awase series♡ I've added a touch of navy linen to the gentle colors (⌒▽⌒) The back is made of thin, 100% white linen. Size: Approximately 29.5 x 35 cm I make each item with care, but as a handmade item by an amateur, there may be some imperfections such as warping or misalignment. Thank you for your understanding (*´꒳`*)♪
