This pattern from Katia used to be available for free. Now, the pattern is for sale by Katia. Here is the pattern link on Ravelry. You may try to contact Fil Katia for the pattern. It may still be available in both English and Spanish.

The free pattern included the lace pattern charts. To make it easier for me to follow the lace patterns, I recharted them with the basic symbols that I’m more familiar with. Since this pattern is now a free download, I’m posting my recharted diagrams here in case anyone would like to use them.

I’ve made some adjustment here and there to suit my taste:
1) The original pattern worked this sweater in 2 pieces, front and back. Then, the 2 pieces are grafted at the shoulders and the sides. But instead, I worked the body in the round up to the underarm. Then, worked the upper front and the upper back. This way, I only had to graft at the shoulders.
2) I defined the neckline by making rows of sc in that area instead of continuing on with the lace pattern.
3) I added a row of sc for the trimming around the cap sleeves.
4) Since I’m petite, I decided to cut back the length of this tunic top.
5) I also added the bottom trimmings. The trimming was a combination of 3 rows of the Linen stitch (aka: Moss stitch) and 4 rows of the Small Shell pattern #222, pg. 158, from The Complete Book of Crochet Border Designs by Linda P. Schapper.

I later made one with long sleeves for my sister. To avoid having to seam the sleeves onto the body, I worked from the shoulder down to the hem. I also worked the sleeves in the round.
