Weekend Knitting compiled by Melanie Falick has a beautiful short cardigan that appears Lacey and light in spite of its gauge of 16 st/ 4" because it is knit w Bergamo wool ribbon. I think it would compliment your eyelet dress well and be quick to knit up. The pattern is called Cache-coeur Bergamo by the designer VÉRONIK AVERY. The Weekend Knitting book was available as an e-book from my library. You could check access at yours.
The book also has quick pullovers, great sock pattern by also by V. Avery, knitted cotton lace edging for pillow cases by ALISSA BAPTISTA, and cute fairy tale finger puppets byPRISCILLA GIBSON – ROBERTS; along w recipes for slice and bake sugar cookies and hot chocolate, and a list of classic literature that features knitting-- fun book!
