When you are young and just have a couple of years for your CV reference contacts I would say yes.
Be sure to make it clear that this is on call work and not job hopping.
Later on when you are an established rock star of the pastry world you can drop them .
You know you are there when the person interviewing you has no need to see your portfolio ( as your rep has proceeded you lol).
Don't put them in with your work history.
When you compose the cover sheet mention the 2 or 3 most successful caterers with whom you maintained a casual working relationship during school.
I liked the description in your initial post, short sweet and you didn't come across like a egotistical a**.
I got the idea it was just for pocket change (lol) during school.
Might not be a great idea to tip a prospective employer to the fact that you are working side jobs.
I would leave it out.
You have just graduated but have been around enuf to know good imaginative decorators can be as scarce as hen's teeth.
That said, if I were to interview you it would be foolish and naive of me to think you went such a long time with no means of support.
Go ahead and cover the span with your freelance work... IMO it would be foolish to hide it under the circumstances.
When interviewing be ready to answer questions re the used of a licensed and inspected kitchen for this work (real question, how are your ethics).
If hired you will most likely be required to sign a non compete contract anyway.
Good luck on your path.
I am almost jealous lol!
Sorry about that.
Trying to carry on a serious "conversation" online can sometimes be tricky lol.
This is my thought process..... a good decorator cannot go for 11 months without someone asking them to do an event cake.
Trying to hide the fact that you do freelance (of course you work from a licensed kitchen ie commissary RIGHT ? ) might leave the new boss a bit distrustful .
EVERYONE does freelance at one point or another (the fast cash is just too tempting) so add it to the resume and get it out in the open.
If hired you will get a lecture (and sign a contract) about work done outside the owner's kitchen (which will be NONE).
Then its up to you to be veryvery discrete about what you do off the clock.
Was that better?
