Getting your measurements correct is probably the most difficult and important aspect of making your own personalised blocks. It should go without saying that correct measurements are necessary to end up with a block that fits well.
If you have no-one to help you take your measurements, or the person helping you does not take them correctly, it will make your block-making process more difficult. If you have a problem, it may be worth paying a dressmaker to take the measurements for you.
The fitting process (making and toile and checking your block) is essential, and if you have no-one to help you with this it may take some time and some back-and-forth with the block and toiles, but it is possible, and it will be worth it.
These Measurement Pages (in the menu to the right) contain the information for taking the measurements needed for creating your personalised blocks. There is a downloadable Personal Measurements table to help you with this.
The use of 3D Measuring Stations (e.g. mPort in Australia)
With the arrival of 3D measuring "Pods" like mPort in Australia, I thought it would now be easy to get your exact measurements, but mPod in Australia only supply the basic measurements (e.g. bust, waist and hips) to the people who use the pods. (I am unsure if this is the same in the USA).
mPods in Australia supply the use of the machines for free to the general public; in order to get people to use the machine their marketing is to sell it along the lines of Keeping Track of Your Weight and BMI. They supply only the basic body measurements to these people, such as Bust, Waist & Hips. They do take much more detailed measurements of the people who use the machine, and sell this on to the Fashion Industry. This anthropometic data is valuable and essential to fashion houses and fashion lines.
While I can understand that they don't give out the information wholesale, I do not understand why they cannot supply individuals with their detailed measurements.
