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).

  2. Thanks for sharing! I love envelope-necklines!

  3. Thanks for tutorial and pattern. I have been looking for one since my first was a baby and this is the first I have found online for free!

  4. Thanks so much!

  5. Hi....U r amazing...thanks a lot for posting free patterns and providing such great pics with detailed info. God bless u...

  6. this is awesome, im going to attempt to adapt it for fleece, figure an extra half inch everywhere will make it work. i really needed a simple top to go with her pjs! shes 8 months, going on 2t. lol

  7. figured id share since it was definately successful.
    it was really easy, great tutorial.

  8. Adorable pattern! Thanks for the great tutorial!

  9. Thanks for that tutorial and pattern, can not wait to try it tonight :)

  10. I have been looking for this pattern for a long time. It's here. thank you!

  11. This also makes a great nighty for babies, just make it longer and wider at the hem.

  12. Thank you for a great pattern! This is such a relief to find and now my grandson will be the best dressed baby on the block.

  13. Thanks for the great pattern and tutorial - I sewed one for a friend's baby.

  14. such a cute pattern. I cannot get it to print. When I print I get your logo and the printed text. No lines appear on the page. Have tried black only as well as color printing. Ideas?

    1. Hi linda, probably you try to print the file directly form your browser. Try to download the file first and than print it. Good luck!

  15. Great patterns, thank you so much. However, I don't understand why a pattern for a 9 month old American baby would fit a 4-6 month old EU baby (e.g a British baby). I can't believe that American babies are so much smaller than British babies? A 2 year old (24 months) American child is only the same size as a 1 to 1 and a half year old English child? Do you know why this is the case?

    1. The sizes refer to the clothing sizes you buy in the shop, which differ in different countries. The EU patterns are the size you would buy in a Dutch or German shop.

  16. Great vibrant colours.. Cute pattern

  17. Could this be done in flannel....if so, what changes would need to be made?

    1. I don't think so, because it needs to be a fabric with stretch.

  18. Thank you for this great pattern!
    I made a shirt for my son, who is a size 98. I simply made the front and back larger in the middle, but now the neck is way to wide. Do you have an idea how to fix that, that is, make the neck tighter?
    Or do you have a pattern for this shirt for larger sizes or a hint how I can make it largert? Thank you!
