It isnt a wise choice having your business named after a word that you yourself cannot even spell properly.
If you the business owner cant spell it, what hope for other people that want to find it by carrying out a search?
It also suggests that you are religious or to do with the church which may not be as beneficial to you unless you are involved with them. For example, I live near to a cathedral myself but if I saw any business venture with that in the name it wouldn't make me presume you named it after where you live, but instead make me think you are directly linked to the Cathedral and the Church and that you may be donating any funds you make towards the Church and its causes. You may find you attract the wrong crowd of people who believe they are taking sewing classes that are organised by the church itself.
I would stick to simple catchy names that represent what you are about..... for example....
Learn 2 Sew
Sew Easy
Sewing 4 Beginners
Start With Stitches
Sew A Craft
Craft-ucation
Sew Together
Best of luck with it tho :)
