Anni building block


Sizes: EUR 32 – 50 (US 0 – 18 / UK 4 – 22)

By combining different blocks of this mix-and-match pattern, you can sew up to 36 different variations!

The pattern includes a bodice with flattering princess seams, and three neckline options: V- or O-neck, and a beautiful combination of a V-neck and a Peter Pan collar.

The three sleeve options are a classic T-shirt sleeve, a beautiful long bell sleeve, and a cold shoulder ruffle sleeve. You can also sew the garment without sleeves.

The bottom options: a beautiful knee-length pencil skirt,  long wide-leg trousers, or shorts with show-stopping bell-shaped leg frills.

Choose a light or medium weight woven fabric with drape. It is recommended to choose a drapey fabric especially for the the ruffles and the leg and sleeve frills for them to drape beautifully. The fabric for the bodice, Peter Pan collar, skirt, trousers and shorts can be less drapey.

A hook and eye

Calculate the total fabric consumption by adding the consumption of the bodice to consumption of the bottom half. Take into account which sleeve variation (sleeveless, short sleeve, long bell shaped sleeve, or ruffles) and which bottom variation (trousers, shorts, skirt) you will be sewing. The consumption calculation for the bodice includes the consumption for all neckline variations.
