Make your hoodie from soft jogging fabric, your rain jacket from PUL (breathable and also with Oekotex quality mark), your shirt from tricot or ribbed tricot or for a cooler sweater the Ottoman rib. To sew a soft body warmer or jacket, use a fleece, teddy cotton or fluff teddy. You can make a summer variant body warmer or sweater from terry tricot, jogging or cotton velvet.
Make a teddy body warmer or jacket with the woolly fabric on one side and a soft cotton tricot on the other, nice for the finish and extra comfortable to wear.
Tip: Always wash the fabrics cold before sewing, of course sorted by color, especially if you are going to work different fabrics against each other. Use liquid detergent to keep the fabrics nicer and softer.
