The crocheted placemat curls up because of the nature of the stitches used in crocheting. The natural tendency of the yarn to twist and the tension of the stitches cause the edges of the placemat to curl inwards. This is a common characteristic of crochet projects and can be minimized by using different stitch patterns or blocking the finished piece. **

For gray plates, a white placemat would be a good choice as it will create a nice contrast and make the gray plates stand out.

Avoid using a dark or bold colored placemat as it may clash with the gray plates and overwhelm the overall table setting. **

Handmade paper can be smoothed by using a variety of methods. One common method is to use a smooth, hard surface such as a glass or marble slab, and gently rub the paper in circular motions to flatten out any wrinkles or bumps. Another method is to use a heated iron on a low setting to press the paper between two sheets of smooth fabric. Additionally, the paper can be placed under a heavy weight for a period of time to help flatten it out. Overall, the key is to apply gentle pressure and heat to the paper to help smooth out any imperfections. **

Overall, a fountain pen is a great choice for writing on handmade paper due to its gentle touch and elegant writing experience. **

For a handmade book, it is best to use a paper that is durable and can withstand the wear and tear of being handled and turned frequently.

Overall, the best paper for a handmade book would be one that is both durable and suitable for the intended use of the book. **
