I made one pair from blue jersey and one from the same black fabric I used for the tie-shirt. I also used the same teal fabric to make cuffs and waist bands. Instead of using a pattern, I just copied another pair of pants and made the new ones slightly bigger.
I also had this fabric left since I decided to make the Viking jacket from a different one, so I wanted to make a romper for cold winter days. I purchased this pattern on Etsy as it promised to be quick and easy and it really was!
The pattern was simple (with markings in four languages: english, italian, french, spanish) and instructions clear and detailed enough (also supported with sketches) even if you were a beginner. It took me about two and a half hours to make the romper, including cutting out the pattern first and then the fabric. If you're looking for a simple but cute romper pattern, I recommend it.
The Viking fabric was a bit thin for winter and since lining was included in the pattern, I chose flannel to line the romper with. I only had white flannel so I used some cotton scraps for the pockets and the cuffs to make it more fun.
I need to buy some buttons though because I don't have any that would match this fabric.
