Sew Valentine's cosmetic bag

To sew a cosmetic bag, you need to prepare one cut of red cotton (plain and polka dots) of size 20x26 for the front side, one piece of white cotton in red polka dots of size 40x26 cm for lining, non-woven fabric, zipper, bronze snap hook and ring, as well as threads and decorative elements.
Modeling patterns. At the first stage, you need to build a pattern. To do this, draw two intersecting circles of the same diameter on a piece of paper (purple dotted line).
From the top of the intersection of the circles (point "A"), lay down the perpendicular with a length equal to the length of the cosmetic bag (green dotted line). From point "B" draw straight tangent lines to the outer parts of the circles, thereby completing the construction of a valentine pattern (red solid lines). The pattern depicted in the diagram can be printed on an A4 sheet in 1: 1 scale and cut out along the red outline.
Preparation of parts. From red cotton, cut out one piece of cosmetic bag, and from white cotton to red peas, 2 parts.
Details from red cotton strengthen from the wrong side with non-woven fabric.
Take the clasp and cut it to a length equal to the length of the straight side of the heart minus 2 cm. To make the edges of the “zipper” of red cotton and polka dots, cut two squares with a side of 6 cm. Fold the two opposite edges of the squares inwards by 1 cm and iron. Then bend the resulting rectangle in the middle and iron. Insert the fastener inside the workpiece and lay a zigzag seam around the edge.
Assembly of parts. On one of the external parts of the cosmetic bag, place the clasp with the lock down.
Cover the workpiece with the lining facing up.
Put a straight stitch along the edge of the workpiece, twist it, align the front and lining details and re-lay a straight stitch, but this time, stepping back from the edge of the fold 2 mm.
This seam will not allow the fabric to get into the clasp during the fastening-unfastening of the cosmetic bag. Now take the red cotton part. Lay a zipper with fabric on it and cover with the remaining part of the lining (upside down). Lay a straight line along the edge of the product, twist it, align the front and wrong parts, and make a fixing seam.
Attach a cotton tape with the inscription "hand made" and a ring to one of the outsides.
Attach a carabiner to the cotton strap.
Unfasten the snake and combine the outer and lining details.
Lay a straight line around the perimeter of the cosmetic bag except for the straight side of the lining. Remove the makeup bag through this hole.
Iron the open edges of the hole inward and close with a blind or outer seam.
Align and iron the product.
Valentine's cosmetic bag is ready!
