Slider
 

I'm sorry I left part that out, I just jumped right in. It was the Supreme Slider, color light pink.

I mostly use my Juki for FMQ. It lives in a SewEzi table. My solution was to just wax the bed of the Juki and the table with car wax. It makes the fabric slide really nicely and no mat to mess with. BTW, car wax also works on the old machines. I wax the beds of my FW's and 301. It keeps them looking nice and seems to help with the tiny surface scratches.

I have a supreme slider, a silicone oven mat and a flying carpet sled from Amazon. None of them made
me a better FM quilter. I gave up on all of them. For me it works better to have the quilt supported. I have a table on the left and an ironing board level with my table behind. My sewing machine sits flush in an arrow table. I turned the arrow table around to have a bigger space in front. For me- this works best.

Ah, thank you! ;)

You can buy a flying carpet sled. It is large and can be cut if you want. Adhere with a bit of tape if needed. Cost is usually under $15
