Besides the obvious sewing items like scissors and pin cushion, there are two items I keep on hand at all times. They are masking tape and tracing paper. Here are some ways they can make your sewing process easier.
Tracing Paper
I use it when I sew clear elastic band (to avoid fabric from over stretching) , laminated fabrics or leather. For clear elastic (pictured above), I layered the strip of tracing paper on top of clear elastic so the clear elastic does not stick to the sewing foot. I sewed lace, clear elastic and tracing paper together. Once you are done with the seam, just rip the paper to remove it.
Masking Tape
1. Use it to mark the right side of fabric.
Some fabrics are hard to tell which side is right and which side is wrong. In order to avoid mistakes, I cut a piece of masking tape and put it on the right side of the fabric as I cut the pattern pieces.
2. Write down the needle size
I often get confused with what needle I’m currently using. I change the needle and keep using it, completely forgetting if it’s 11, 9, or a ball point needle. Sewing needle sizes are hard to tell from just looking at the needle. Now I have a solution. Whenever I change a needle, I write down the needle size on a masking tape and stick it right above the needle so I know exactly what I’m using.
3. Cover the edge side of bones
Instead of creating a bone channel, I use a plain white masking tape to cover the edges of bones and sew it directly on fabric. This only works for plastic bones like the ones shown in the picture, not the steel bones.

私が良く使うソーイングアイテムの紹介です。
まずは100キンで買うトレーシングペーパー。
レザーをミシンで縫うときもこれさえあればちゃんと縫えます。
他にはラミネート加工された生地や、透明ストラップを縫い付ける時なんかにも。
一緒にトレーシングペーパーを縫い込めば、ラミネート生地などのべたべたした部分がミシンの押えに引っかかって縫い目が乱れることを避けることができます。
縫い終わったら、ゆっくりピリピリとペーパーを剥がすだけ。
マステも常に傍にあります。
布の表面と裏面を印つけるのに使ったり（私は表にマステを貼ることにしています）、ボーンの切り後の始末にも使います。
あとはいつも使っている針番が分からなくなっちゃうので、針を取り換えたら番号を書いたマステをミシンにぺたり。
Find me elsewhere:
The place is a bit hard to find, unless you have Google Maps or exact direction to the place. It is about a minute walk from the exit 7 of Meiji Jingu Mae (明治神宮前駅) station (Fukutoshin line or Chiyoda line). The outside looks like an ordinary apartment building without any distinguishing sign. The name of the building is “Jingu Heights(神宮ハイツ)”. I double checked because it felt as though you are going into someone’s apartment without permission. Coromoza is on the 4th floor of the building. 
I hope this review is useful, and feel free to email me if you have any questions.
. Mine are 24 cm in length, but I kind of wish I went with 21 cm. They are quite heavy and I think they would have fit in my hands better if they were a bit smaller. Anyway, I hope you will enjoy the video! If you have any video requests, please let me know.
