Sometimes a simple linen fabric is all that is needed for the project, but it is still fun to go fabric shopping and see all that is out there. In a big fabric store, they will find many colors and shades of linen fabric, and they can pick the perfect one for whatever purpose they are going to use it. If they want to explore various other fabrics, then they will find plenty of them when fabric shopping, as well. They can check out silk to see how it feels and whether or not it would work for the items that they want to make.
Every fabric works differently when sewn and used for various projects, and they need to be a bit more careful with some fabrics than others because they are more delicate. If they want to buy chenille fabric, then they need to learn how to use it before they do that. The same goes for silk and chiffon. They need to work with the right thread and needles to get all of these fabrics sewn well. If they want to keep things simple with any project that they are working on, then they might just want to go with cotton fabric because it is much easier to work with than other fabrics.
Some fabrics are less expensive than others, as well, and if they want to go with one of the least expensive fabrics, then they can choose cotton. It can still be used for many purposes, and they will still have fun when they shop for it because it comes in so many colors and patterns, but they will save money with it. If they are doing an extra-special project, then they can pick out some of the more expensive fabrics and get just the number of yards they need.
