Before you start cutting anything, you need to make sure you have a decent set of dressmaking scissors or a rotary cutter and mat if you want the best results. Do all your cutting on a vast and flat area. Dining room tables are perfect for this.
For the best cuts, your fabric should be ironed first, before putting on the patterns.
Iron your pattern pieces with a dry iron before you place them on your fabric. This will greatly increase the accuracy of the final product. If you have tape on your pattern for adjustments, simply use a press cloth placed on top of the pattern or iron around the video.
Pin the pattern pieces to your fabric or if you prefer you can use pattern weights and then outline the pattern with chalk. Pin the corners of the pattern first and then put pins at regular intervals between those.
Use the full length of your scissors. When cutting, use as much of the scissor blade length as possible, stopping just before the end. Only use your sewing scissors for cutting fabrics and nothing else.
When sewing over a side-seam while undertaking a new hem on jeans, the material can get very thick on the side-seam and needles often break. A handy hint is to flatten this section down with a hammer before sewing over it which makes things much flatter and easier to sew.
Always wash and dry your fabric after you purchase it and before you cut your patterns out of it for your project. You need to do this so that the fabric shrinks, and means that your final product will shrink much less. If you are working with a non-washable fabric like wool, you will need to take it to a dry cleaner and get it cleaned and then pre-shrunk.
When sewing, try not to focus on the moving needle, but instead on your sewing guide to get the best straight and tidy lines. If you don’t have a sewing guide on your machine you could try using tape placed on your machine where you want your guide; painters tape is great because it doesn’t leave sticky residue behind when you take it off.
Use a good quality thread. Trust me; a poor quality thread will cause a lot more hassle than the benefit of the small amount of money you save.
If you are making something that will need to be turned inside out when you have finished, clip away any excess material in the corners to make it easier to push the corners out when you turn it right side out.
