Back to the TopThanks. I’m almost done but having trouble understanding you tulle instructions. Fold in half and I sewed in the center; gathered and split in half. But sewing it into the fins along the hem it only fits at the top of the fin is that right or do I have it bunched too much
The idea is to fill up the fin with tulle so it is puffy and some of the tulle can peek out. You can adjust it to fit into the space evenly.
I can’t get it to print full size pattern. Help
When you go to print it sometimes will fit the paper. You will need to select the “full size”.
Hello,
I tried to download the tutorial, but only the pattern showed up…. Can you please let me know where to find the tutorial?
Hi Sarah! There are four pattern downloads for the four different sizes and then one that says “mermaid costume photo tutorial” right underneath.
I’ve almost finished this costume and I’m on the find of the tail and cannot figure it out. The top seams of the back and front fin are very disparate lengths, and if you see the bottom portion that so match in length, (which is how the image looks to be sewn) you end up with find that point straight down. Please help.
Hi Lysbeth,
The fin is higher in the front center to allow the child to walk and not step on the front of the fin and lower in the back because there is a slit to allow the legs to move, so the fin can drag a bit in the back.
