 Here are the tools and the materials that I'll be using for this tutorial. Bus cup pattern from my previous tutorial. If you haven't checked out my tutorial yet for bustier with bus cups, I'm going to put the link down on the description box so please do check it out. Bias tape, polyurethane bra foam. I bought this bra foam from Aliexpress and I'm going to put the link below at the description box if you are interested. Fabric scissors, a piece of fabric, bust ball or bust ham, my portable sewing machine with zigzag stitches, and my industrial sewing machine. So as you guys can see for the bus cup base pattern, I have three panels and I put one centimeter of sewing allowances for each corners. And I also made a different set of patterns for the bus foam cup. The difference between the two is on the base patterns, each corner or seam has allowances. Contrary to the bus foam cup pattern, I didn't put any sewing allowances at the lower part of the panel one. And with panels 2 and 3, I didn't put any allowances at the center seam and at the top parts of the panels. Because for the bus foam cups, I'm going to sew or join each panels using a zigzag stitch to avoid the bulking at the seams. Again, for the base patterns, I used one centimeter of sewing allowances for each corners. And for the bus foam cup, I also used one centimeter but excluding the lower part of the first panel, the top parts of panels 2 and 3, and the center seam. Later on, I will demonstrate how to sew the bus foam cups. For the base, I'm going to cut these patterns on the fabric on the grain line. And I am going to snip out the notches at the bus point and at the lower part of the first panel. So these are my three panels, panel one, panel two and panel three. First, I'm going to assemble panels 2 and 3 together. Face the two panels right side to right side and pin everything in place. Once the panels are pinned in place, I am going to sew it. By the way, I used one centimeter for my sewing allowances. I also used different threads so you can see how it is sewn. Next, I am going to snip out the bus point notch but not beyond the sewing or the stitch line. This will help me press the lower part of the bus cup properly and neatly. Using my bus pole or bust hem, I am going to press out the seams of the lower cup. Next, I am going to connect the first panel to the lower part of the bus cup. I am going to match the notches and pin everything in place. Once the panels are pinned in place, I am going to sew it. So there you go. Next, I am going to give this a press for a clean finish. So this is the base for my bus cup. So next, I am going to cut out the patterns for my bust foam cup on the polyurethane foam fabric. You can trace your patterns directly on the foam but I like to pin my patterns in place instead. Either way, it's good. Just don't distort the foam and get the correct shapes from the pattern. Next, I am going to connect these two panels together. Face the panels at the seam and to connect or join both panels, use the zigzag stitch. And here is my portable sewing machine. I am going to use the big zigzag stitch first. Then later on, I am going to use the smallest zigzag stitch for securing the seams. By the way, make it sure to position the panels where the needle is positioned. And make it sure to align the bust point notches. Put down your foot pedal and start sewing. So there you go. This is how it looks like because I am not satisfied with one stitch line. I am going to make another stitch line but this time I am going to use the smallest zigzag stitch to secure the seams. Next, I am going to attach the first panel. It is the seam procedure like what I did with panels 2 and 3. Face the panels together so it's like you're puzzling. Position the seams directly where the needle is going to start the stitching and put your foot pedal down and start sewing. There you go. Now we have assembled the bust foam cup. And of course, I am going to make another round of stitch line at the seam to keep it secured. So this is the assembled bust foam cup. Next, I am going to conceal the seams or the stitch lines using my bias tape. I am going to do this at the back part of the bust foam cup. So next, as I've said earlier, I am going to conceal the back part of the bust foam cup. So this is the front and this is the back. Using my bias tape, I am going to conceal the zigzag stitches line. So using my bias tape, I am going to conceal the zigzag stitch lines. I am going to do this first at the lower part of the bust foam cup. Cut the bias tape according to the length and pin the bias tape in place. Next, I am going to top stitch the bias tape side by side, like this one. And I'm going to cut out the excess of the bias tape. And this is how it looks like on the first seam. Next, I am going to do the same procedure here at the top stitch line or the center seam. Basically, it's the same procedure. And there you go. This is the back part. So the reason why I did this is because we don't want our clients or customers to see the messy zigzag stitches. So this is how to conceal it with bias tape. Next, I am going to assemble both base and foam cups together. To do this, place the right side of the base at the back part of the foam cup, where we did the bias concealing. Again, right side of the base facing the back part of the foam cup. Pin everything in place. And next, I am going to sew first the top part of the bust cup by 1 centimeter. Next, I am going to give this a press. By the way, guys, while I was pressing, I have sent or pushed all of the seams here at the foam part. And I'm going to top stitch the seams by 2 eighths of an inch. Next, I am going to trim the excess. So next, I'm going to give this a good press. So now that everything is pressed, I'm going to top stitch the base and the foam cup together, combining them both. By the way, if you can see, there's an excess foam here, and that is okay. We can always trim it out. The important thing is always follow the base, because it's the true size. Next, I'm going to top stitch both base and foam cups together. So here's the complete assembled bust cup. To give this a clean finish, I'm going to press this cup once more on my bust ball or bust hem. And this is how it looks like on a model. By the way, for the part 2 of this tutorial, I'm going to teach you guys how to attach the underwire channels, how to attach the bust cups on the actual fabric, and of course, how to sew the bonings properly. By the way, guys, comment down below if you have any questions, and I'll make it sure to answer as quickly as possible.
