For most quilting projects I use 100% Cotton. Occasionally I will use vintage sheets or something else that is a cotton/poly blend. Try not to mix fabrics as 100% Cottons and Blends will wash and wear differently. That said, if you are making something like a memory quilt out of old clothes or something similar where you are mixing a variety of fabric types it will probably be fine – just keep in mind that different types of fabric will wear differently over time.
I generally do not pre-wash my fabric I like the sizing that is in the store-bought fabric because I feel like it makes it easier to accurately rotary cut. If you stick to high-quality 100% cotton quilting fabrics that come from the independent shops or the higher-end selection at JoAnn, Hancock, etc. you should not have a problem with colors bleeding, etc. If the fabric is older or lower-quality I would suggest prewashing before you start cutting. There is more information about washing finished quilts here.
Probably one of the most intimidating parts of beginning a quilting project is choosing just the right fabric. Here are a few simple tips to help in that process.
- Color: Above is a collection I used for a recent quilt. First I picked a balanced variety of colors – especially lights vs darks (or in this case lights vs brights.) Then I picked different shades of the same color. Look at the oranges – they are all part of the same color family, but they are all different shades. This will give your quilt a lot more visual interest. Fabrics colors that are too matchy-matchy (i.e. all the oranges are the same shade) will make your quilt feel flat.
- Scale or size: Currently there are some gorgeous large-scale graphic prints available. They are so fun to work with and make a really interesting quilt. But if every print you use is the same scale (size), your quilt will look out of control. There will be no place for your eye to rest and the beautiful big prints will just get lost. What we need is contrast. Not only in color, but in scale. So again, I divide my fabrics into groups by scale: Large, medium, and small.The large and medium scale prints are both busy and colorful but the design repeats are closer together in the medium scale prints. The small prints almost read as solids. They aren’t solid, but if you step back and squint your eyes they look like a solid color. These prints provide thecontrast for the busier large and medium size prints to really show them off. They provide a place for your eye to rest. You can use actual solids – which I sometimes like – but the design becomes more flat. With a small print ‘solid’ you get more ‘texture’ or interest to the quilt.
