From my experience, which is not that big, I think you can do it. Make sure to match the needle to the fabric and than tread to the needle. I would go with poly thread because it is often stronger than cotton. Check you bobbin and your top tension as well! If you need more info on tension the HQ has a great video called TNT -Threads, Needles, Tension. The reason why I said match your needle to the fabric is because the deco fabric is stiffer and quite a bit thicker than quilting cotton. I have worked with a really puffy batting, and I am not a big fan. The quilting looked great, but it was a challenge. Using a double batting would make that bedspread way too heavy. if your client would pay for it, i heard that wool batting behaves very nice when quilted. i have not tried it yet. Good luck!
