德累斯顿盘计算器 🌸
计算德累斯顿盘拼布块的叶片裁剪尺寸和布料用量。
How to Use the Dresden Plate Calculator
Enter the finished plate diameter, the number of blades, and how many blocks you need. The calculator returns all cutting dimensions and yardage for both blades and background squares.
Cut blades using the calculated wide and narrow end dimensions. You can use a commercial Dresden Plate ruler for accurate cutting. Fold and press each blade tip before assembling the circle.
Appliqué the assembled plate to the background square. The center circle covers the raw edges at the center. Use the calculated center circle diameter (includes seam allowance) for your template.
常见问题
德累斯顿盘有多少瓣？
传统德累斯顿盘块使用12、16或20瓣。瓣越多外观越圆；瓣越少则呈现更有棱角、更具图形感的样子。
德累斯顿盘的瓣需要专用尺吗？
专用的德累斯顿盘尺让按正确角度裁瓣容易得多。不过你也可以根据我们工具计算的瓣角度画出楔形来制作模板。
德累斯顿盘的中心如何收尾？
将瓣缝成环后，中心的毛边用一个圆形贴布片覆盖。把圆裁得比开口略大，将缝份向内熨烫，然后缝合到位。
