If you are one of those crocheters who want to learn how to make their own garments and still have many doubts, here are some tips so that you can shape those projects you have in mind.
First what I do is choose a point that I like and that combines with the garment model that I have in mind (that combines according to you of course, you have to like the combination that you are making of points and garment model, this is what I mean ) and of course choose the color and type of material you are going to use.
Once you have chosen the point and the model of the garment, it is important that you define the measurements that it will have. For this, it is generally very useful to "stand" on a garment that you like the way it fits, and that is ideal for the model you have in mind. In this way, when you calculate the number of points and shape of your fabric, it will be much easier.
The basic measurements that must be taken into account are the bust measurement to know how wide your garment will have, the measurement of your armhole and the length you want. Generally when we take measurements and calculate the stitches that we have to make, we must bear in mind that, as we knit our fabric it can shrink or stretch, therefore it is very important that before starting with your garment you make a sample for example 10cm x 10cm to know how the thread reacts with the point, needle and tension that you are knitting.
To give it the desired shape in the neck, sleeves, back (depending on the garment you are going to make) you will surely have to make increases and decreases, therefore, it is important that you also show how decreases and increases "behave" with the chosen point. So you will know in advance how many decreases or increases to make and in which parts to give the shape you want to each part of your garment.
Regarding the seams, I have tried several ways of doing them and the one that has been much easier and with the best result in the end, is to join the parts of my garment with slip stitch (last stitch, slip stitch, there are several ways to tell ). In this case, you will have to take into account how many stitches to make in each point of the garment parts so that the seam looks good, without causing the garment to stretch or shrink. For example, when I sew garments that are made entirely of double crochet, I make 3 dwarf stitches on each double crochet. It is important that you check, because this will depend a lot on the tension with which you work, so as you go sewing, check that the fabric fits well.
Well crocheter, these are all the points that I take into account when designing and making a crocheted garment, they are also tips that can be taken to make garments on circular needles.
I hope they help you.
Happy creative journey.
