Enlarging a pattern using a grid is a straightforward method to scale up your design accurately. This technique involves drawing a grid over your original pattern and then drawing a scaled-up grid on a new piece of paper, transferring the pattern details square by square.
Here's how to enlarge a pattern using a grid:
Understanding the Grid Method
The core principle behind grid enlargement is breaking down the pattern into smaller, manageable sections represented by each square in a grid. By transferring the contents of each small square on the original to a corresponding larger square on your new paper, you effectively enlarge the entire pattern while maintaining its proportions.
Steps for Enlarging a Pattern
Follow these steps to enlarge your pattern using a grid:
-
Prepare the Original Pattern:
- If your original pattern doesn't have a grid, carefully draw one over it.
- Choose a grid size that is appropriate for the detail level of your pattern. A common size is 1 inch by 1 inch (2.5cm by 2.5cm), as mentioned in the reference. Use a ruler and a pencil to draw clear, consistent squares.
- Number or letter the rows and columns along the edges of the grid on your original pattern. This will help you keep track of corresponding squares.
-
Draw the Enlargement Grid:
- On a new sheet of paper (large enough for your enlarged pattern), draw a new grid.
- The squares in this new grid must be larger than the squares on your original pattern. The ratio of the new square size to the original square size determines your enlargement factor. For example, if your original squares are 1"x1" and you want to double the size, draw 2"x2" squares on the new paper. If you want to triple the size, draw 3"x3" squares, and so on.
- Ensure the new grid has the same number of rows and columns as the grid on your original pattern.
- Number or letter the rows and columns of this new grid to match the original grid layout.
-
Transfer the Pattern Square by Square:
- Reference Step 2: Pick a square on one side of the original pattern (e.g., square A1).
- Find the corresponding larger square on your new paper (square A1 on the new grid).
- Reference Step 2 (continued): Note where the pattern lines enter and exit the original pattern square. Observe their position within that square (e.g., does the line cross the top edge halfway? Does it touch the left edge one-quarter of the way down?).
- Mark those corresponding locations on the edges of the larger square on your new paper. If a line enters the original square halfway across the top, it should enter the larger square halfway across its top edge.
-
Sketch the Line Segments:
- Look at the shape of the pattern line within the original square.
- Carefully sketch a similar shape between the marked points in the corresponding larger square on your new paper. This shape should look like a scaled-up version of the original line segment.
-
Repeat and Connect:
- Continue this process for every square on your original grid that contains part of the pattern.
- Once you have sketched all the line segments in their corresponding larger squares, connect the lines smoothly from one square to the next to complete the enlarged pattern outline.
-
Refine the Enlarged Pattern:
- Step back and look at the complete enlarged pattern.
- Refine the lines, smooth out any jagged edges, and correct any parts that don't look quite right compared to the original.
- You can then darken the final lines and erase the grid lines if desired.
Using a grid allows for controlled and accurate enlargement, making it a popular technique for artists, crafters, and designers.
