I am not a professional in the field of stitching, but according to my experience the best way to improve the design and design quality of the product should the usage of the commercial stitching machines that only requires the design as input and the rest work it does itself.
I came across this question many times that "How to stitch the Large Embroidery Designs" or "Which hoop size you use for Large Embroidery Designs"
Please note that the Question should not be about the hoop size but instead, it should be about the type of machine used.
You cannot stitch the large embroidery designs with a home-based Embroidery machine. This type of designs are meant for Commercial Machine only.
Just have a look over this image and Video of 12 Head Multi Needles Commercial Embroidery Machine:
(the above image and video is taken from the Embroideryshristi admin Album, from this forum. This image and video is a property of the embroideryshristi)
The above Machine is Commercial Machine used for Large Embroidery Designs.The most popular multihead embroidery machines are 2, 4, and 6 heads. There are also 3, 8, 10, 12, 15, 20, 24 and 30 head multihead embroidery machines.
Now, question may arise "What should be the hoops size of Large Commercial Machine, if i want to stitch the full Design".
Again this question is diplomatic. There are various different kind of Commercial Machine are available like 250 area,500 area and so on. Size of hoops depend on your requirement. What is your requirement that is how bigger the designs is???
But this doesn't mean that you cannot stitch the large embroidery machine without having a specific machine.
Like Home Embroidery Machine, where you use the large embroidery designs after splitting it, the large embroidery Machine can be used in the same manner.
The following two examples will clear your doubt. But before moving to the example please note that, unlike home embroiderer, Commercial person always stitches in mass and are very much concerned with loss of resources.
In the above image, since the size of the neckline is large, it is splitted in to two part.After splitting the Neckline, this designs is stitched by 12 heads large commercial machine in bulk.Generally Commercial person do not stitch one designs they stitch the designs in bulk as shown in above image.
This will reduce the waste and the machine will be used to optimum.
After stitch the designs in bulk, this designs are cutted down in different part and stitched together at the time of sewing. Final it will result in full dress.
Thus, like home based embroidery machine, even large commercial machine use the splitted designs (as the size of the designs is greater than Machine area)
Now, suppose you want to stitch the full designs with stitching it in a part?
No problem, it is possible to do this with the large commercial machine in two ways
1) You must have the Large Commercial Machine with a large hoop as per your requirement. 2) You can use it as a single head machine This is the real answer to the question that "Which hoop is used by you for full embroidery designs"
Please note that there is no specific hoops size. You cannot change the machine every time with the change in design size. There are designs with 10 inches,20 inches,30inches in height. You cannot judge the size of the hoop unless you do not produce the standardized product.
Please have a look over this project on Full Embroidery Designs:
Now, generally we do not have such a big embroidery machine.
Then how this designs is stitched?
The Commercial Machine shown at the starting of this article is a 250 Area 12 head Multi-Needle Machine. Further, this design is large than the size supported by this machine. (mean it is not possible to stitch such designs in bulk as shown in the above neckline case)
So how these designs are stitched?
These Full Embroidery Designs are stitched by using a single head. It means that only a few heads from a total of 12 heads are used to stitch this design.
So single head is used to stitch the full embroidery designs.
Of course, now you cannot stitch the designs in bulk.
In the case of neckline designs, every head produces one design, whereas in the case of full embroidery designs since the size of hoops is small, the size of another head is merged to make it large and thus it will reduce the number of designs produced.
In simple terms, 12 heads commercial machine will be equal to 12 single head machines.
So if you use split neckline as per your hoop size then you will get 12 neckline designs, but if you want to go for full embroidery designs then in that case it will not get fit in single head machine.
So you will merged another heads and stitch the designs by using single head only. The other heads will not be used.
This may result in less efficient use of the machine. This is because, Machine will not use all heads and thereby the number of designs stitch will be low as compared to previous one. Further this may result in loss of resources too.
So, full embroidery designs is stitched by making some modification in machine. It is stitched by using single head only.
So what will be the optimum size of the machine?
Answer to this question depends on your requirement. What is your requirement. Of course, the answer to the question of selection between home based and commercial based embroidery machine can be answered with knowing your requirement.
You must have the large commercial machine or use splitted designs.
I get this video on internet.Just have look over this Embroidery Machine video. In this video you will find the working of Commercial Machine. By looking the size of machine you can easily say that this machine can be used for stitching the large full embroidery designs. [smg id=214 type=av]
At last, please note that in the case of a multi-head machine, size is not measured in total, but instead hoop size is measured between the heads.
I short, it may be possible that designs may be larger the hoop size (single head) but if you look over the machine 12 heads in total then it will of course look smaller
I am not a professional writer, but I had tried my best to make you explain. I am not an experienced guy, i am still a beginner. You may correct me if I am wrong anywhere.
