Last summer I took an IKEA SY sewing machine to Lithuania. It was packed into a regular suitcase surrounded by clothing and got there just fine. Coming home I had only one suitcase, and had to abandon the sewing machine. The young man I gave it to at the airport was thrilled to get it. So that trip cost me $70 more than expected.
Last night I saw a Janome sewing machine that weighs five pounds. Hancocks has it on sale this next week for about $50. That's the one that is going with me this year. It does straight sewing and zig-zag. Nothing else. That's enough for me. I think it's going into my purse. LOL
