In Pixie Hollow, tailoring plays an important role as the more people tailor, the more outfits become available.
To start, you need to visit a local tailor, my example comes from Bobbin's Tailoring Nook's, which is found in Springtime Orchard.
In order to open up personal patterns, you need to do community patterns, which if I understand correctly, the more you do, the more options are offered to the new pixies that get created.
After choosing Community Patterns, it starts you off with a list that you can do.
To clarify, the numbers you see aren't how "many" you have to do, it's how many points you need in order to open up the next level of patterns. Now since I've been doing it for awhile my numbers are a lot higher. The first set of patterns you can complete at 500 and they steadily go up from there. I didn't do an exact count but it only took about 5-7 rounds of tailoring to get 500.
After choosing the pattern you want to make, it allows you to choose what color to make one. I haven't found any benefit from picking one color over another so far.
Step 1 is coloring the fabric (Roly Poly Dyeing)
It operates very much like a game of Breakout
where you have to keep the ball moving over the pattern until it's all covered or the timer runs out.
Step 2 is cutting out the fabric. (Caterpillar Cutting)
This game is basically leading a caterpillar chasing after some cake to cover all the dots from start to finish. It's not terribly difficult but there is still a period of adjustment.
Step 3 is lining up the pattern. (Pattern Placement)
It's a small jigsaw puzzle where ants deliver your puzzle pieces.
Step 4 is sewing the fabric.
You have to wait until the spider is completely over the hole and click it at the right time. The closer you get, the better quality the final product becomes.
After completing all 4 steps, you see your score and get your points.
So that's it, rinse, repeat and enjoy. The more you tailor, the more patterns open up for you and you also help the community in the process.
You also receive a badge after so many completions.
