baby romper. The catch? It was size Newborn (so up to 8 pounds?) So I thought I would share how to alter the pattern to fit your needs. Really you could alter the pattern to be any size you like with these tips. Also learning how and what to alter can help you alter other patterns as well. So to start things off here is a common question I get:
Can I enlarge the pattern to make it a larger size? The answer? No. If only it was as easy as printing the pattern larger, or blowing it up in a copier. The truth is that not all places of the pattern grow when going up a size. You only add space/length to a pattern where the child grows. So let's get started.
romper you can follow the crotch line down and add length to the bottom of the leg which will lengthen the leg room since kids grow taller. Also I would add width to the leg so the fit is more comfortable around the leg. To determine the amount of length you should add measure the length of the pattern (subtract seam allowance from top and bottom and typically hem allowance the this pattern has a cuff so you can skip that) Then measure the child from the crotch to the bottom of the leg to decide how much you need to add to the bottom.
What to choose? If you are only going up a size or two you could likely get away with adding to the top only, if you are going up several sizes you will want to add room in the torso area as well. For all sizes you will want to add width in the chest.
Then you are good to go. The pattern is altered and ready to sew in any size. You can use many of these same tips in adding room where your child has grown (compared to the pattern piece) to alter any pattern you need, all you need is a pretty good understanding of how the pattern goes together and what the pieces are for.
Hopefully that helps!
