Based on the provided reference for prepackaged satin blanket binding, you need the total length of all four sides of your project plus an additional 10 inches.
Applying satin binding, particularly for finishing edges like on a blanket, requires a specific measurement to ensure you have enough material for a neat and complete finish. The method outlined in the reference offers a straightforward way to calculate the required length.
Calculating Your Satin Binding Needs
The core calculation for determining the necessary amount of prepackaged satin blanket binding, as described in the reference, is simple:
- Measure the Perimeter: Measure the length of each of the four sides of the item you are binding (e.g., a blanket).
- Sum the Sides: Add the measurements of all four sides together. This gives you the total perimeter.
- Add Extra Length: Add an extra 10 inches to the total perimeter measurement.
Calculation:
- Required Binding Length = (Length of Side 1 + Length of Side 2 + Length of Side 3 + Length of Side 4) + 10 inches
This formula directly comes from the reference: "To determine how much you need, add length of all 4 sides together and add 10″."
The additional 10 inches provides crucial buffer room. This extra length is typically used for:
- Overlaps where the binding ends meet.
- Handling corners smoothly.
- Accounting for any slight inaccuracies in cutting or sewing.
Having this extra length prevents you from running short right at the end of your project.
Example Calculation (Illustrative)
Let's say you are binding a blanket that measures 60 inches by 80 inches.
| Side | Length (inches) |
|---|---|
| Side 1 | 60 |
| Side 2 | 80 |
| Side 3 | 60 |
| Side 4 | 80 |
| Total Perimeter | 280 |
| Add Extra | + 10 |
| Total Binding Needed | 290 inches |
So, for a 60"x80" blanket, you would need approximately 290 inches of satin binding.
Understanding Packaging
The reference also notes, "(I needed 2 packages.)". This indicates that for the specific item being bound in the reference's context, 2 packages of the binding were required to meet the calculated length. The number of packages you need will depend on the total length you calculate using the formula and the specific yardage or length contained within a single package of the binding you purchase. Always check the package size to determine how many you'll need based on your total calculated length.
By following this method, you can accurately estimate the amount of prepackaged satin binding required for your project, ensuring you have sufficient material for a professional finish.
