Vollrath (used to be Wearever), #5314. Heavy 13 gauge. I haven't found anything better, and I have had several. And, since it's rimmed, it does double- and triple-duty as a pan to put under pie to catch juice drippings, a sheet cake pan, a pan to roast vegetables, and several other things. Though I have been wanting to try the Goldtouch that Shear Stupidity linked above. I have a Goldtouch loaf pan, and it's the best loaf pan I've ever used. But, since I already own two of the Vollrath sheets, I have no need at this time to buy another. Here is a link that might be useful: Vollrath 5314 Sheet

I recently purchased a few half sheet pans from a restauraunt supply house. This thread gave me an idea - coincidentally related to what MTRG posted - and I did a quick experiment: I baked two batches of Toll House cookies, induction bake, as identical as I could except one batch I placed on an upside-down pan. Both batches on parchment. The upside-down pan clearly had more even results, both across the pan and across the individual cookies. Obviously it will take a few more runs, a few different types of cookies, and trials with multiple racks to see if I'm really onto anything, but it was an interesting result. I will say that removing the upside-down pan from the oven was a bit awkward.

Kathi, I don't know if you still need the dimensions for the pack and play mattress but here you go. I just had my daughter measure hers. It is 38" x 24" x 2". I may be needing the tutorial you linked. My grandson just turned 10, but my daughter has baby sat for some time and uses the pack and play a lot. We were just told she is due Jan. 31, 2014! We will be finding out what the baby will be, so I may be making sheets cause she isn't finding anything she likes so far. Tami

I have just recently been googling this very topic. I was surprised to read that LL Bean sells very good quality cotton sheets. I didn’t even know that they sold sheets. The other thing I learned is that you should not get caught up in going for the highest thread count. After a certain number ( I think they said 300) it isn’t a major factor. Sleeping on heavy cotton sheets is one of life’s little joys IMO.
