Planning several beginner sewing projects will increase your creativity and handcraft skill. Also, if you do it right, you can also produce a lot of them to be sold to your friends and relatives. There is nothing wrong to learn some sewing techniques for a certain product. The key is to know which product will you make later. After deciding the product then you can learn the needed method to make the product.
As for newbies, going for simple patterns on your beginner sewing projects is a wise choice. This is because the simple sewing technique tends to be easier to mix and match. Also, the simple technique is easier to be done compared to the more difficult techniques. The example of simple sewing techniques are the simple straight lines and not-so-intricate sewing with a few frills or embellishments.
As for your choice of products, simple things such as keychains, pillows, or blankets are the safe option with no intricate techniques needed during the sewing process. It is best to avoid clothing because it needs some advanced techniques and it is not suitable to be included in your beginner sewing projects. Know your product and hone your sewing skill in order to take a more difficult project.
