The first of two about the making of fine fabric is The Dream of the Lacemaker from 1910, which explores a miracle in the life of a maiden who lives alone with the artisan in question, her grandmother. The old woman is prevented by advanced age from embroidering the lace she must supply. The young girl saves both her aging relative and herself through her faith in the Virgin. When granddaughter and her granny together fall asleep, Mary materializes to complete their piecework for them: a stitch in time. The lass takes the finished product to a Gothic castle, which houses a medieval-style court, and where the castellan rewards her richly for her lacy labor.

A poor, elderly, and tired lacemaker is helped at work by her granddaughter. One evening, before going to sleep, the latter prays to the Blessed Virgin to come to their aid. During the night, the Virgin appears and leaves a large quantity of lace in her basket. When they wake up, the little girl and the old woman exult in front of this miracle. Then the child hastens to offer his wares at the neighboring chateau, where the ladies offer him a purse full of money. On his return, they give thanks to the Virgin.

In this delightfully pretty film we see Dolly and her grandma who is tired and sad after a tedious day at lace making. Her eyesight is failing and she cannot make enough lace now to make both ends meet and putting her work on one side falls asleep. Little Dolly looks at her dearly loved grandma and then at her work. Taking it up she endeavors to do some, but in vain, and kneeling down prays for her grandma and then she too falls asleep and dreams that a vision appears making yards of lace. With joy Dolly opens her eyes to find the dream true. Awakening grandma she shows her the lace and then rushes off to the castle where she begs to be admitted and on entering displays the lace to the ladies of the castle, who are enraptured with its exquisite design and pay her an immense sum of money for it all. Bounding out of the castle through the grounds and homeward and rushing in with the good news, they are indeed rich now and the story closes with ultimate happiness for the loving old lady and her grandchild.
