Patterns aren't cheap. Seriously, I was browsing through through the look books at Hobby Lobby the other day and some of them were as much as $20. Tack that on to the price of fabric and other supplies and suddenly sewing your own clothing becomes very expensive. Thankfully, you can make your own patterns using your own clothing that you know to fit well. I'll show you how to make a simple blouse pattern using a top of my own. I used Scotch Postal Wrapping Paper as my pattern paper. I found it at Target for about $5. It gives you 30 feet of paper, so it will last a long time. I used paper because I like to lay my pattern piece down and trace the shape directly onto my fabric. If you think you'd prefer to pin the pattern to your fabric and then cut it out, paper may not be the way to go for you. Muslin fabric is another great material that would allow you to pin the pattern piece to your fabric. It's also nice because it can be folded up and stored away when not in use. Lay your garment down on the paper and determine the middle of the top. Mark right above the collar and right below the hem. Draw a rough outline of one half of the top. When you get to the sleeve, do your best to fold it back so that you just see the armhole. Sketch the curve as shown below. This first pattern piece I'm working on will serve as the back of the pattern. Sketch the outline of the slightly higher, back collar. Stop once you get to the half marks that you previously made. Now you'll need to sketch an outline outside the dotted line to allow for seam allowances. To determine how far apart the rough sketch line should be from the final outline of the pattern you'll need to take what materials you're working with into consideration. For example: The lace top I am using has a stretch quality to it. If I want to use this pattern to make a top with a non-stretch fabric, I will need to make the final pattern outline a good amount wider than my rough sketch. However, if I was using a non-stretch garment to make my pattern I wouldn't have to allow for as much extra fabric. It's always better to have a too big pattern and therefore a too big top than it is to go too small. Don't be afraid to be generous. Extend the outline by about 1.5 inches along the sides and about 1 inch at the armholes and collar. Extend the bottom of the top by several inches to allow for hemming. Cut on the line and fold the pattern over making sure that the crease is on the middle marks you made previously. Trace so that you have a perfectly symmetrical pattern. Repeat the same process for the front piece of the pattern being sure to trace the front part of the collar this time. Now for the sleeves. Fold a piece of paper and position it underneath the garment and the pattern. The fold should be parallel to the top of the sleeve. Trace the curve of the front pattern piece. Leave plenty of extra room for the sleeve to be hemmed. Remember it's better to go oversized than undersized. You can always take the shirt in if it is a little too big. Cut out all of your pieces and press to get rid of creases and you're done! *Update* I recently used this pattern to make this cute little top. Click on the picture for the full tutorial!
