What to sew?
For the raincover you need vodootliv fabric. These materials belong to technical, but you can buy them in the regular store. The label usually indicates the level of moisture protection (e.g., dry10 – this fabric holds a 10 000 mm/cm2 day). Among water-repellent fabrics, there are "breathing", in a cloak of similar material you will feel most comfortable with. Vozduhoplavatel indicated by the arrow directed upwards. Since you are not going to like this coat to go to multi-day treks, you can choose cheaper materials, calendered nylon or Dacron. You can sew the cloak and the old technology, made of cotton fabric impregnated with made with your own hands.
Style and calculate fabric
Raincoat-poncho can be semicircular or of two squares. Measure the length of the product. In the first case the calculation is done. If the width of the cut is greater than the length of the product on a semicircular cloak poncho will need 2 lengths, plus about 20 cm at the notch for the neck and treatment of NCDs. In the second case, the product length is the diagonal of a square, so you first need to calculate the direction of this geometric shape. You can calculate in two ways. If you do not want to remember the school geometry course, simply draw a square of this size on graph paper and measure the sides. You'll also receive the pattern by which to cut out the fabric. Double the side of the square and add 20 cm You will need a split zipper. Its length is equal to the length of the product.
Cutting
Semicircular cloak poncho cut out exactly the same as bell skirt. Measure the neck circumference find the radius. Add it to the length of the product. Lay the fabric wrong side up, find the middle of the edges and put a chalk point. Draw a semicircle with centre at this point. To draw the notch from a level to a perpendicular to the edge and postpone it the radius of the recess. This will be the center of the recess. Draw a circle, cut out detail. Hood make some of the remaining pieces. It may consist of two squares of sizes 20x20 or 25x25 cm
Assembly
The front edge of the hood from hem, turning down the fabric twice on the wrong side. Treat the bottom of the cloak. The lower edge of the hood align with the neck and pin. Try on a poncho, adjust the hood and pristrochite. Design options top quite a lot – the hood can be, for example, at the front with Velcro or removable, can be top cut to make drawstring, etc.
Square cloak
Cut the fabric into 2 equal squares. Put them together, right sides together. Make the neck. This will draw a sector of a circle with center in one of the corners. The radius of this circle are calculated by dividing the neck circumference by 6.28. Baste and sew the sides of the squares adjacent to the neck. One of the squares cut on the diagonal, that is, from the neck to the lower angle. Other operations are the same as in the manufacture of semi-circular cloak.
