Need help with sewing

Go buy a few yards of broadcloth in colors that match your current bedding, then start making pillow cases. This will give you practice on measuring, cutting, adding seam allowance, turning corners, and making a fold down casing. Once you have made a few you will have the basics down and can move onto simple patterns. Always have a warm iron and a board set up so you can press seams and hems as you sew.
