Have you ever sewn a beautiful garment only to find the sleeves don’t fit right? The secret to comfortable, well-fitting clothes often lies in one simple thing: properly shaped armholes. Today, I’ll show you how to make armhole templates that will change your sewing forever.
Why Armhole Templates Are Game-Changers
Most sewing frustrations come from not understanding the relationship between armholes and sleeves. Many sewists think armholes are complicated, but they’re actually quite simple when you know the basics.
Think of armhole templates as your personal fitting tool. Once you make them, you can use these templates on any pattern to get the perfect fit every time. No more uncomfortable sleeves or strange bunching under your arms!
The Four Basic Armhole Types You Need to Know
There aren’t endless armhole variations to worry about. In fact, you only need to know about four main types:
- Tank top/sleeveless armhole
- Knit fabric armhole
- Woven blouse armhole
- Jacket armhole
For many sewists, the tank top and knit armholes might be identical in size. The woven blouse armhole is slightly larger to allow movement in non-stretchy fabrics. The jacket armhole is the largest, often accommodating shoulder pads.
Each armhole type pairs with specific sleeve patterns. When you understand this relationship, fitting becomes much easier.
Finding Your Perfect Armhole Size
The best way to discover your ideal armhole size is simple: look at clothes you already love wearing. That favorite t-shirt or perfectly fitting blouse holds the secret to your personal armhole preference.
Here’s how to find your perfect size:
- Pick a garment with an armhole that feels comfortable
- Lay it flat on a table
- Employ a French curve ruler to outline the edge of the armhole.
- Take the measurement of the armhole curve in inches.
Write down this measurement. This number is your personal armhole size preference. Keep it handy for future projects.
Making Your Armhole Templates: Step by Step
Creating your own set of armhole templates is easier than you might think. Here’s how:
What You’ll Need:
- Cardboard or template plastic
- Pencil
- Scissors
- French curve ruler
- Your favorite garments with different armhole types
Creating Your Templates:
- Start with your favorite knit garment. Lay it flat with the shoulder seam straight.
- Place your cardboard under the armhole area. With the help of your French curve, replicate the precise shape of the armhole onto the cardboard.
- Cut out the shape, making it slightly wider than the actual armhole for easier handling.
- Label this template “Knit Armhole – Front” or “Back” depending on which piece you traced.
- Repeat for the other three armhole types (tank top, woven, and jacket).
When finished, you’ll have a set of templates for both front and back armholes in each style. These become your personal fitting tools for every future project.
How to Use Your Armhole Templates
Now for the fun part – using your templates to improve any pattern!
Let’s say you have a blouse pattern but want to make it from knit fabric instead of woven. Here’s what you do:
- Place your knit armhole template on the pattern, lining up the shoulder seam point first.
- Swing the template out to meet the side seam.
- If the armhole on the pattern is larger than your template (common when switching from woven to knit), redraw the armhole using your template as a guide.
- Extend the side seam up to meet your new armhole line.
- Repeat for both front and back pattern pieces.
The key is that your armhole can pivot between two fixed points: the shoulder seam and the side seam. This allows you to maintain the same comfortable fit regardless of the pattern you’re using.
The Magic of Matching Sleeves to Armholes
Each armhole type has a matching sleeve that fits perfectly. When you use your knit armhole template, make sure to use your knit sleeve pattern too.
This is important because:
- A woven sleeve in a knit armhole will feel too tight
- A knit sleeve in a woven armhole will feel too loose
- The wrong match creates uncomfortable garments
By keeping your armhole templates and matching sleeve patterns together, you’ll always have the right combination.
Troubleshooting Common Template Issues
Sometimes your template might not line up perfectly with a pattern. Don’t worry! In most cases, you’ll only need to extend the side seam until it aligns with the armhole template line.
If you’re making a jacket without shoulder pads, remember to adjust for that change first by lowering the shoulder point the same amount as the pad height before applying your template.
For very different body types or unique fit preferences, you might need to make slight adjustments to your templates over time. This is normal and part of developing your personal fitting system.
Frequently Asked Questions About Armhole Templates
How to draw a perfect armhole?
Drawing a perfect armhole requires patience and practice. Start by marking your key points – shoulder and underarm. Use a French curve ruler to connect these points. The front curve should be slightly deeper than the back. Always test your drawing on muslin first before cutting your final fabric. Make sure your lines are smooth and flowing. Take your time with this step as it’s crucial for a good fit.
How to create an armhole?
Creating an armhole starts with basic measurements. First, measure the armhole depth from shoulder to underarm. Then, mark the width at the chest level. Connect these points using your curved ruler. Remember that the front armhole needs more curve than the back for movement. Keep your marks clear and precise. Test the shape on a scrap piece of fabric first.
How to get an accurate armhole?
Accuracy comes from precise measurements and proper tools. Take measurements while wearing the right undergarments. Use a flexible measuring tape for body measurements. Double-check all numbers. Make a test version in muslin to verify fit. Adjust as needed before cutting your good fabric. Minor modifications can significantly impact the overall fit.
How to draft a sleeve pattern for beginners?
Sleeve drafting starts with your armhole measurement. Measure around your completed armhole template. Add ease depending on the style you want. Draw the sleeve cap height. Create the curve using your French curve ruler. The sleeve’s total width should match your bicep measurement plus ease. Start with a basic fitted sleeve pattern. Make adjustments based on your style needs.
How to calculate armhole?
For armhole calculations, start with the depth measurement from shoulder to underarm. Next, measure the width from side to side at chest level. Then measure the total circumference around the armhole. Add half an inch for comfort in fitted garments. For loose garments, add more ease as needed. Always measure twice to ensure accuracy. Consider the fabric type when making your calculations. Different fabrics may need different amounts of ease.
