This was how I drafted a very simple maids apron from a yard square (actually 150cm by 100cm) of simple white cotton, physically, but should be straightforward to draft in Valentina.
"Required 1 Yard square, ( I actually had 150m by 100m but had a lot of spare material. so it should be possible do this with a 1m square fabric piece.)
"Fold Fabric halfway, and on fold draft as follows…
From top center on fold A makr B bust (Example: 8 inches), C Waist line and D base ( typically the length of fabric, but may be made shorter if needed.
- From A square out to A1 ( 1/2 Shoulder to shoulder front Example: 8 inches) .
- And B square out to B1 (1/4 Bust circle Example 12 in. )
- And C square out to C1 (1.4 Waist circle Example 9 in)
- D-> D1 same as B -> B1
Curve through A1, B1 ,C1, and then a smooth diagonal to D1. Pattern piece for apron front is (clockwise) A, A1, B1,C1, via the curve drawn, D1, D, A., which is cut on the fold to create the apron front.
On the other side of the fabric place 2 rectangles approx 4 in (width) each to 1yd (ie length of material) This will produce a waistband and 2 shoulder straps. when cut. (The spare length can either be sewn into the waist-band for stiffening).
The waist band is folded over and sewn centered on the waist line vetrically , I.e there is a hem./seam approx 1 inch above and below the wasitband, and on the center line of the front peice when cut. The shoulder straps are swen folded over to 2 in width, and sewn to the top left/top right of the front."
To put the apron on, place wiastband at waist, and taking the ends of the waistband pull to rear, and tie in bow. Then place shoulder straps over shoulders crossing at mid back, loop straps over waist band and tie ends in bow.
This design should ideally be cut in stiff cotton or starchable fabric"
This is a very simple pattern/design I drafted quickly, I’ve omitted a neck line, others here probably have more complex designs or improvements."
