The way I've always removed beads is with pliers, that way you don't ruin the fabric and the thread stays intact. Just go along the stitching line and remove from the seam allowance, making sure the machines foot can move freely. Taking all the beads off in the seam allowance will make pressing your seams easier. Caution the beads will fly everywhere so protect your eyes. As the others mentioned above you will need to sew some beads back on after you sew the seams. Also a tip for pressing beaded silk chiffon cover your ironing board with a fairly thick pile towel or something similar, lay fabric right side down DO NOT USE STEAM and lightly press. I reccomend pressing the beaded fabric before you line it. Hope that I was able to help, let me know if you need any more help, I specialise in couture bridal and evening wear. Look forward to seeing photo's of the finished gown.
You need to measure the armhole you are stitching the sleeve too, which would roughly be the cap of the sleeve if you take it from a sleeve pattern. BTW The cut you make to the center circle will give you straight edges these are stitched to the armhole also, so this will need to be included.
I like the look of these sleeves, I would do them as a circular pattern. They're similar to a flounce on the hem of a skirt. It should look like donut, cut to the center circle and as you open and pin to the armhole it will give you the desired look. Hope that I was able to help, let me know if you need more details. I would love to see the finished garment.
I love this dress, I have to agree with educo it would be easier with a dressform. I had a look at the picture that was a close up: Start by treating this as a circular skirt (that's pulled up over your bust). Allow extra length for the center front section that dips over the bust. Know you have a base to start from, you have to mark the center front panel the finished width, the panel at the front is pleated so allow for pleats. Under the arm is more circular sections or even bias cut godets its kind of hard to tell if I had time I could test some it on some fabric, this section you may need to trial and error. Then it's a matter of applying the ribbon and trimmings, diamante. I'm a dressmaker so whenever I have to patternmake I look at the garment one section at a time so that it makes it easier, if you need any more help let me know good luck!
The dress looks gorgeous!, great job. Just a tip next time you sew beaded silk, or anything beaded mark where the stitching line is, crack the beads with pliers along that line and a bit either side so the presser foot on the machine can move the fabric easily. (warning: when cracking beads put your hand over the pliers so that beads don't hit you in the eye or face)
I've made a dress with a similar sleeve, I cut the pattern to look like a leaf narrow at one point then wider then narrow again. Cut this on the bias if possible. Another way is to use the top section of the sleeve pattern, measure from the sleeve head to the length you want. Depending on the fabric being used you may need to put some elastic into the top of the sleeve so it stays on your shoulder. Hope I was able to help
You are able to die the tulle and lace, you would have to know what the fibre content is to buy the appropriate dye. Tulle can either be nylon, polyester or even silk. The lace could be all natural fibres like cotton or it could be polyester and nylon net. An easy way to modify the bodice section is to buy some ribbon, trims or lace to match and insert it into the side seams even center front depending how wide the trim is and how much you need to let it out. You should work out how much you need to let it out. Then divide this by how many seams will have the trim insert. The next step would be to re-cut the waist of the skirt to fit back to the new bodice, I couldn't tell in the photo's if the waist is gathered, if it is then let out the gathers without cutting. Hope I was able to help in some way, let me know how it works out.
From what I can see in the picture it looks like the satin strip is doubled, so there's a strip on the outside and one inside so you don't see seam allowances. I think it sandwiches the chiffon in between, you can machine 2 of the seams than hand sew the last to close it, which should be done from the inside where it won't be visible. Each section of the chiffon is separate and joined by the satin. I hope I was able to help and not confuse the situation, I'll try to draw or photograph what I mean and work out how to get them on here, I'm a designer/dressmaker and new to this site so I'm still working out stuff. Look forward to seeing photo's of the finished gown.
