Chosing a clothing size:
The European clothing size is equal to the length of your child in cm, measured without shoes. Always chose a size larger than the size of your child, unless the size of your child is exactly the same as the clothing size. Children clothes don't come in small, medium, large and extra large. The patterns on my website are sized medium. Is your child bigger than average, chose one size larger and shorten the sleeves with 1 à 1,5 cm (0,4 - 0,6 in).

  1. What a cute dress. Thankyou for the pattern :)

  2. Dat zijn nogal cadeaus ! Uw naam "droomfabriek" waardig ! Heel vriendelijk dank hiervoor.

  3. I recently bought some sweater knit fabric to make a Christmas dress for our two year old daughter and this is the perfect pattern. Thank you so much!

  4. I love your patterns and I've used them a lot and blogged about them. For example:
    (I only make for my grand-daughters, not professionally.) However, I am not sure about the long sleeved dress pattern in the larger sizes (I haven't looked at the smaller ones.) Your pictures in the tutorial show a more or less A-line shape, perhaps just slightly curved in at the waist. However, the patterns pieces don't correspond to that shape. Because the middle section is square (straight sides) The pattern seems to go straight down almost to the bottom and then just do a little flare near the hem. In fact the width at the hem of the pattern piece is only about 1" more than the middle and top. Have I missed something? (I've taken a photo I can send if I haven't be clear enough what I mean.)

    1. Hi Mary Jones, yes I like the dress for young ones more A-line shaped and for the older ones I like the dress more straight.

    2. Thanks for your reply. Personally I like it a bit more flared to allow for running about and climbing trees, but it will be easy to make that adjustment.
