This is a 2020 pattern and seam allowance is included in the pattern pieces. Further there is a detailed sewing description with photos of all the different sewing steps. The pattern consists of ready-to-cut paper pieces that will allow you to sew all the items mentioned. All pattern pieces are full size and the pieces do not overlap. When you purchase the pattern you can pick your download version, A4 or Letter size.
The clothes in this pattern are to be worn without a diaper. That is why you find briefs and bloomers in this pattern.
Most clothes are made with lightweight cotton fabrics. I used a fat quarter pack with quilt fabrics. The line is Lill Red in the Woods by Riley Blake. The baby briefs are made with knit fabric and I use fold over elastic for the edges. Here you can see how I use fold over elastic: How to use Fold Over Elastic to finish edges
The dolls in the photos are my personal Zapf Creations BABY Born ® dolls, 43cm. I have designed the patterns especially to fit these dolls but PLEASE NOTE that my patterns are NOT official Zapf Creations ® BABY Born ® patterns. I create all patterns by hand in my workroom in Houston and I have no affiliation in any way or with any doll manufacturer whatsoever.
