If this is the case, a space of your own, just for your hobby, might be nice. A shed workshop is basically a retreat area for you to enjoy your hobbies with no interruption.
I like to give plenty of notice about when my crops are going to be held. This gives people a chance to think about what they are going to work on, and what to pack up to bring along. Allow a couple of week’s notice if you can and be in touch with people about the day throughout that time. Talk it up. Say what you are going to be doing and ask your friends what they are thinking of working on so they will think about bringing only enough supplies to work on their particular projects.
If you don’t want to sew it yourself, whether for time or personal safety, find a dress maker locally. You can talk it over with them and show the ideas you have for an ideal dress; they can add their professional input and make something you’ll be happy with. This way the dress will still be original and let your personal style shine through; not all designers are seamstresses.
Industrial Best Sewing Machines (aka commercial machines). These are the superfast machines used in production work. They are dedicated to producing one type of stitch, but you can be sure, it’ll do it well. There are industrial machines for straight stitch, zig-zag, serging, blind hems, buttonholers, rufflers and more. They’re very expensive, but if you’re sewing for a living, they may be well worth the expense.
Aside from actually doing them on your own, you can also ask another printer to work on it. You can pass the design of your choice to them so you will get the right one for you. Of course, you need to ask them about additional charges since they will use your design instead of the one they do. This will ensure whether you need to prepare additional money just to have them printed out.
For safer stitching, use the pointed end of a wooden shish kabob stick to help steer your little pieces. The kabob stick will keep your fingers away from the needle.
A little fearless creativity and a bit of sewing will get you clothes that let you standout. Perhaps your friends will get on the idea and turn to you to jazz up their threads. Then maybe a serious career in fashion design is not too distant.
